I am very open to kissing/making out with clients I meet. I especially enjoy it when the client I'm with happens to be a good kisser too! I agree, kissing is a big part of the overall experience so that's why I choose to do it.
I am not fan of the RM messenger app. I have downloaded it and actively use it to respond to client inquires but you're more likely able to get a hold of us using the old version of messenger. IMO.
