Truth be told,
I don't have experience in this area, but from what I have been told, kissing and touching is more of a sensual thing and alot of people do it because they care about the person and it is like a way to connecting physically.
No offense but you are just the sex toy.
Craiglisters, Grindr, etc people want sex with no strings attached. The guys who are gay or on the DL or just experimenting want to get pleasure from you and use you. That really is it.
If you ever watch certain porn, alot times Sean Cody, or Corbin Fisher, they dont kiss they just start having sex.
Kissing can sometimes have more meaning than sex, as weird as that sounds.
Besides a guy did not come over to kiss you, he came to do you.
The only time I can see that happening is if a guy really likes the full aspect of being witha guy, and he doesnt get to do it often, and that guy will kiss, and hug, and cuddle. And yes they are out there.
I hope i did not offend you but I think you really have to like someone or have them get to know you to have them be more sensual.
