Why doesn't penetration feel good?

I guess a little about my sex life;
ive been mastrubating since i was about 4 or 5, the same way till now. I rub on things.
I lost my virginity 2 years ago to a uncirumsized guy. im with an uncircumsized guy now and we've been together 11months. His penis kinda hurts me, i dunno if its the uncircumsition or the was its curved. Hes about 5.5-6.5
i've been with one guy who was cicumsized and it didnt hurt. But other than that penetration just doesnt get me going.

freehugz2012, Welcome to the world of real women. Only in books and movies does every woman have a glorious orgasm every time she has sex.

In real life, only about 20% of women orgasm from intercourse only. The reason for that is that your clitoris is where your sexual pleasure is. Most women does not get the stimulation on her clitoris to trigger orgasm during intercourse. For a few women, the vagna is sensitive. Even then it is normally only the entrance and the outer third.

For the rest of us we have to stimulate our clitorises while having sex. This can be done in a number of ways:

Find a position where there is access to your clitoris. Either doggy, yu on top or a position where your feet are in the air. Use a small clitoral vibrator or you or your partner's fingers to rub your clitoris.

Find a position where your clitoris gets the stimulation needed. A specialized position like coital alignment technique (c.a.t.) or you on top. There you can grind down to give your clitoris the contact it needs, change the angle, depth and speed of penetration.

Circumcision or not, and a bent penis should make no difference. Make sure you are well lubricated. Get a water based sex lubricant and use it.

Seeing that you are a humper, you might have to practice masturbation with your fingers and hand for a while before you will be able to orgasm from that.

In the mean time you can get off by humping his leg/thigh, arm, get on top of him with his penis flat on his belly and straddle him while humping over his penis, or if he is on his belly, his ass cheeks.

Best of luck!
