I was wondering if anyone could help me. Me and girlfriend have really good sex but there is a problem when I enter her from behind. If we are in missionary or she has her legs around me neck etc. everything is ok and it's great. But if I enter her from behind the tip of my penis hits against somthing which causes her quite a lot of pain. The easiest option would be not to use these positions, but apart from when I hit it she loves it when I enter her like this and it drives her wild. I just wanted to know if anyone knows what I am likely to be hitting, how not to hit it etc.
Thnx for all the help
Most likely you are hitting the nerves and muscles around her pelvis/tailbone.
WHile it MAY not be as comfortable for you, if you STAND behind her and bend yoru knees to enter her doggie style...this will keep you erect penis pointing more doward towards her "G" spot and away from her pelvis!
The cervix gets hit a lot during sex in certain positions, personally I enjoy it, but some women find it uncomfortable. try the same positions but don't go in so far.
In my experience, it's all a matter of how the woman's body is angled in relationship to the man's. I have found that doggystyle can be very painfull in certain positions, but if I lean my upper body down very low with my butt up high in the air, I have no problem. I can't promiss that this particular postion will work as well for your girlfriend as it does for me, but you should experiment with different angles until you find the one that is right for the two of you.
Thnx for all the help guys, I will let you know how it goes.
