Sex.... Masturbation probably would have been my second choice, and close runner up. Because i can do it so much more, and i dont have to worry about the other person being in the mood. But sex is just so much more enjoyable when you are doing it. With masturbation, its just you... Oral isnt that fun after about an hour, but sex can be fun for hours.
If I had to pick one it would be to giving head. I love the intimacy of sex and the way that it feels but there's nothing better then getting someone off and the feeling somone instanly get hard in your mouth.Plus I can't cook and I'm not very clean so it makes me feel better With that being said it's a commited relationship thing like having sex is-just as intimate.
i chose intercourse cuz it gets down to the point alot better...all the other stuff... aside from anal which i would never engage in anyway, to me is just stuff you do to get warmed up..
