When I have sex, there seems to be a lot of friction and I have a hard time getting it all the way in. After a while when I have an orgasm, the sex seems to be much better because of the extra lubrication. After having an orgasm, I'm still hard and can keep going for a long time. I have never talked about this with my girlfriend or any past girlfriends because it's too embarassing and none of them ever mentioned it. Am I a freak or do other men keep having sex after they have their orgasm? Also, do women find this gross?
