Only about 30% of women achieve orgasm in penetration.
I think that feeling like a woman has much more to it then orgasms, it's a big part of your personality - do you feel like a woman when you do the grocery shopping? when you read an amazing book? when you go to work? being a woman is something you are, and feel it all the time, orgasm or not...
Can you reach orgasm in other way but penetration? if you can then it'll be very nice if your lover will spend the time and effort making sure that you'll have one while having sex with him whether if it's through oral sex or masturbating your clit or whatever works for you.
I think you should have an honest talk about sex with your partner to make sure you are both having fun in bed. To me taking the responsibility over your own happiness in bed and out of it is a big part of being a woman.
