Wasn't sure whether or not to contribute to this, but, why not...
I've been getting massages for about 2 years and two of them stand out as the extremes of this conversation. 1) Pretty beefy guy who is popular here in the forums who gave a very good massage on a table (about a year ago). He got nude (at some point during the massage, I like when they surprise like that), but when it came time for the HE, he did it very mechanically and when I glanced at him, he was staring up and out in space while it happened. No kissing. 2) My last massage was with another very popular guy here in the forums and it had been said that he will go pretty far with guys he likes. Well, did he! However, for me, he turned out to not be my type...though good looking, just 'meh' in a general sort of way. However, about 1/2 way thru the massage (which was very good, btw, and I wish he had stuck to that), I guess he got so excited that it turned into more of an escort session and I think he would have fucked me (er, no, no, no, no, no) if I had let him. He ended up getting off, but I didn't. The session itself went way past the hour scheduled. Boat loads of kissing.
I have not run into someone who is completely non-sexual yet. I don't go into sessions thinking it HAS to happen, but if the guy is hot, I sure don't mind if the extras happen.
