the adverage of most surveys say that 70% of women don't have orgasms from sex alone. this is extremely normal. It wasn't until my 5th partner (my fiance now
) that i had an orgasm with another person and that wasn't from sex. I've realized it takes feeling comfortable with the person your with, as well as feeling strong enough to express what you want. Oral sex before actual intercourse is a great way to make sex feel better, but make sure you actually have an orgasm first. Sorry it is normal and it just takes some work from both you and they guy.
There is a reason our clitorous isn't in our vagina... think of how painful that would be during childbirth!!
