It's all about the communication.  The conversations aren't "easy".  But they don't have to be "difficult" either.
It comes down to being honest with yourself and with them about what 'services' fit into each box.  Example: if he gives you a call and say you feel like going to see a movie.  You go to dinner and a movie and even hang out later.  That's friendship.  However, If you end up swapping blow jobs, that's not friendship.  Or maybe, blow jobs are fine, but it depends on whether it is during his normal work hours, or on afternoons when he isn't working.  Or, it depends on who initiates.  Or, who gets to top who.  
Whatever the definition is for you and him, as long as you both (1) respect and (2) keep communicating, then it can work.
I always feel that this is true regardless of what type of relationship you have with a person.  
I even hold that true for colleagues/subordinates/bosses at work who become outside of work friends.

I understand your point but believe me some gay men in their 50s and 60s text like teenagers and love it. 

And this is where I hit the "too much dialogue" problem.  Guys who offer a massage and I ask if they are trained.  When I want a massage, even if I want a massage + more, I still want a good massage.
I was a LMT for a lot of years, and I really prefer someone who knows what they're doing.  And, I might want a HE or more (at a higher rate).
For me, there is nothing worse than someone advertising massage (instead of body rub) and not knowing how to give a massage.

I agree. You can tell a lot by the medium someone chooses to contact you by. My older clients phone me to book. They never initiate the booking with a text but will respond to my confirmation text. They never use email or messenger apps to contact me. 
Younger / Millennial clients seem to use WhatsApp or Telegram. Those kind of messaging apps. 
Gen X tend to email or text. Sometimes they message me via Twitter DM. 
Of all the methods I prefer it to be via text or WhatsApp because I can then respond discreetly and at the appropriate time. It’s not always possible to answer a phone call and if I’m in company or in public it’s not easy to discuss services over the phone. However if I’m somewhere discreet then a phone call is best if the client has a lot of questions. 
 

Slightly off-target on the topic, but totally relevant.
I recently read through a white-paper on the methods used by various people based on the generation.
Baby boomers prefer face-to-face, phone, or paper.  Many struggle with using apps. Gen Xers prefer phone, email or desktop apps.  They find texting intrusive, unless they are from family. Millennials think phone calls are intrusive.  Texts and social media is fine/normal, but hate depersonalized messages.  They accept apps and mobile sites with ease. Gen Z (Zoomers) avoid phone calls and will ignore most of them.  Texting directly is weird.  They prefer social media, and expect apps with direct messaging to their apps.  Couple this with RM's changes and you get a nice overview of how to reach your target market.

Answer to title question: yes. Every client, no, but most, yes. 
No masseur is obligated to provide a HE, but almost all clients want and expect one, especially from an independent masseur advertising on m4m platforms. Unless the masseur explicitly advertises “therapeutic only” or similar phrasing, with appropriate pricing to match, the norm is to provide some level of erotic elements. What those are and how far they go varies widely.
I agree with @nycman’s post in almost every respect.
Full service during a massage (i.e. penetration) demands escort pricing and client agreement on said pricing beforehand. Otherwise you’re leaving a lot of money and self respect on the table. Please don’t do this, for your sake, and for the sake of others in the profession who have to deal with incredibly unreasonable client expectations of us to provide escort service for a massage price.
If you’re not skilled at massage, I recommend sticking to escort service. There’s nothing more disappointing than a massage from a provider who has no idea what he is doing. You can learn, of course, but until you develop your skills, I recommend not advertising massage.

So, I'll speak in the minority (maybe).
You are giving your power away.  You are turning yourself into a victim and you should take a breath for a moment.  Regardless of the fact that we don't have all the details, that's not important.  We aren't involved and can only respond to the details you've shared.  We are neither judge nor jury.  My opinion is only based on your current information.
You need to accept that you are giving him your power.  Sorry.  And I know it is scary.  It is probably because you are 'embarrassed', 'ashamed', 'afraid', <fill-in-the-blank> of him revealing or outing you.  This is really about him stalking you and taking advantage of your giving him your voice and power.  That doesn't mean ignore it and hope it goes away.  You do need to take your power back.
Three possible suggestions:
Suggestion 1: Tell him you owe him nothing and that if he continues to harass you, you will go to authorities.  You consider his behavior bullying, abusive, and harassment, and unacceptable.  You are ceasing all communication and further attempts by him will result in you going to the police.
Suggestion 2: Stop ALL communication.  If he calls, hang-up without saying anything.  If he texts, block the texts.  However he communicates, do NOT respond.  You're reaction is a lever for him to control you.  If you don't get riled, then he has no control.
Suggestion 3: Go ahead and report it to the authorities.  Talk to an attorney and listen to their advice.  You do not have to lie about it.  You don't have to obfuscate.  If need be, tell them the truth.  The issue here is about escalating behavior and stalking. 
Just my tuppence.
Just for the record, I am not a lawyer, nor do I play one on TV.

Whatever your relationship, it’s important to define and maintain boundaries. That’s the key.

I have had luck with this as well. So my original regular provider and I became fast friends and we did have the very serious talk about when it's the job and when it's not. We both completely agreed on his to handle that and eventually it grew into becoming am one of the closest relationships I've ever had with someone. He's no longer working, but that never stopped us from talking every day and seeing each other when we wanted to. 
And with my current regular, that too grew to be a very good friendship and now it's come to the point that, as long as I let him know beforehand, I can go to his place just to chill with him or while he's out working and wait for him to come back. Have a key to his place and everything. And we had that talk as well, but that one was very quick because we already knew what that fine line looks like. 
And one final provider I'm actually building that relationship with at the moment. The one is still new, but we both see it becoming a friendship. 
For me personally, I believe as long as you are open and honest with each other and can have those talks about work vs friends, it really can become a good friendship. Honesty and clear communication are key, as well as chemistry between the client and provider to be able to get that connection.

Sure it's possible.   I have 3 clients that were (and are)  friends.    It requires a serious conversation about responsibility and the fine line between work  (escorting)  and friendship.   The lines cannot be blurred.   If booked,  I expect to be paid as with any client.    Because they have been friends,  my responsibilities to them are not any different.     I would say I have several clients (who I met from booking)  who are "friendly with me"  if I see them outside a booking.    Not sure I can say we are "friends",   but I haven't had any issues in this area to date.

This comment is totally uncalled for. Either you are saying rgsnva is a liar or you are blaming the victim. Neither is acceptable.

It sounds like he's trying to create a scary situation for you because it's easier to get what he wants amidst the darkness of fear.  So maybe flip the lights on him.  Dispel that darkness by letting him know that if he continues this ridiculous course of behaviour you will have no hesitancy contacting the appropriate authorities, and that your patience is now running thin.  Your time with him was based on the reasonable understanding that no donation for his time was being expected or requested.  It was a hookup that went badly - those things happen.  It should not rob you of your power or turn you into a target.  Assure him that he has more to lose since blackmail is a felony in most places, and can result in serious jail time if he decides to continue with these absurd antics.

I've had the same initial reaction.  And recently had a last minute change of plans.  The provider asked to push it back a couple of hours.
The difference for me was he was willing to meet the original time and asked a favor after explaining his reason.  In return, I offered a different day/time or the original.  He agreed to the alternative and thanked me.  The encounter with him on the new appointment was FANTASTIC. 
We were communicating and had developed a rapport.  That made all the difference.

I'm not sure how I feel about this.  I understand that the provider's time is worth consideration.  And, many a provider has been scammed or had their time wasted.
But, at the same time, the client is dealing with an unknown factor.  When booking an experience, a client doesn't want to end up feeling disappointed.  Many a client has been scammed.  They need to work through to make sure the provider is a good choice.
10 texts... hmmmm...  
I'm not sure how to quantify "serious" in this context.  Does it mean "if the client is booking" or "if the client is considering booking" or "if the client could be persuaded to book"?
I guess everyone has their own opinions.

Every provider I've known who did porn was great except 3 in particular. I don't care if the guy does porn or not if he delivers is what matters.
