Hanging out in mixed company, I used to seem to get the girl
I don't think it's a profession as a whole.
I am a talker though, I love the sex part, but I want it to be fun too. I find that somewhere along the conversation it turns 'heated' and at some point we disappear into the night.
The size thing is funny, because it does matter, however, too big can be bad also. I am not a 'large' lover

but even I have to be careful sometimes I don't knock things around....I think that's a lot of being a lover too, sometimes a lady wants to be ravished, but she wants to keep her ovaries intact too.
My wife is a tiny Japanese woman 5'0" like 98lbs

...most positions just don't work.
So I'd say a confidant man, that can carry a conversation about the lady and himself (rather than his yacht, car, house in the keys, all the women he's had, etc), is affectionate, but not overly touchy at first, is just a bit of a 'jerk' in a jokingly manner that's not too much, and above all takes his time getting to the end of the night whether sex is in the cards or not. I have found not trying so hard for it and it comes. It helps to be able to dance to, whether or not you are good, just moving around together makes the woman so much more receptive (I guess though if you do a horrible job it could backfire).
All I have to go on is in shape or out of shape, when I ended out with my friends they always were surprized at the little circles I'd get myself into.
