I'm very embarrassed and disappointed I guess because I'm 26 and have had a few different partners. But never have I ever climaxed. I love sex!!! And sometimes I feel close. So I tried masturbating and that's when I found out I have no trouble doing it myself. (Just using the clitoris).  Is this normal?? What can I do to change it??? I want to enjoy sex like everyone else!! Please help!!!!
