Hi when a guy gives a woman an orgasm why do they always afterwards..

Because men and women have a different chemical balance, usually it's the opposite, it's the guy rolling over but she could just not want you to think she's real clingy.

I think you need to learn that sex means more to a woman than a man most of the times. Maybe the woman has more feelings for you than you have for her. If this is true you should tell her. Sometimes the hardest thing for a woman to do is try to stop loving someone but if you don't see her as a serious partner and she does then you should tell her exactly how you feel. If you do love her though, tell her!Don't let her walk away from something true because she thinks you aren't serious.

Sex is more emotional for girls - you may just have to grow up and learn how to deal with them.

Because maybe the guy you are talking about only wants to sleep even though she may tell you other wise.

I guess that women just want to feel closer after sex and a man just wants to roll over and go to sleep?? This is a indication that emotion is a part of the female personality and what's wrong with snuggling or cuddling after sex between both partners?

Maybe it's because she wants to feel closer to you, which is why she snuggles you.

Maybe she's tired, which is why she rolls over and goes to sleep.

Maybe she's hoping you'll be as enthusiastic to cuddle up with her after she's reached orgasm (hell, man, you should be more than willing to do this -- she just let you into her most intimate places, and you can't hold her for a few minutes??).
