Just ask. It's not sleazy to ask. You may get a yes, no, or maybe with stipulations. Surprisingly some people are hyper gung ho about filming. However, just because they do porn don't assume they will be eager to film with you. And if the guy you chose initially says no, his attitude may change if you become a regular and he knows you better.
From my experience... I got a variety of responses from various working guys (after asking of course). I haven't filmed anything, yet, but I ask because one day I might go through with it.
- Three of my regulars are very eager and willing to film whatever without hesitation with me. Two did porn, with one probably being more known than the other.
- One of my regulars filmed with clients in the past and at one point was willing to film with me if I wanted. However after finding a number of the clips on pornhub like sites he won't film with clients any longer.
- One regular is willing but it would cost extra to film.
- A new hire was willing to film if I wanted as long as it was for private use only. If I planned to put the vid online anywhere even if it was a free site he would want additional compensation. I assured him if we did film it would remain private. No additional costs would be incurred if it remained private he said.
- The only other regulars I've asked (one who did porn and one who didn't) flat out said no.
I guess the closest filming I've done is a clip I filmed for @tristanbaldwin for his justforfans site. It was mainly a sexy video where he teased the viewer. I wasn't on cam. No one wants to see that. LOL
ADDENDUM:
I forgot to add 2 other guys I've asked aren't necessarily regulars but I've seen them a few times. They both are willing to film as long as they are disguised in some way. One has done porn and the other hasn't.
