Me and my boyfriend have been having sex for over a year. It's great sex that's not the problem, the problem is I can't get an orgasm. The only time I get an orgasm is when he plays or uses a vibrator on me. Is there something wrong with me, anybody have any ideas or tip to help me out?

You are very normal. Many, if not most, women cannot orgasm from intercourse/penetration alone. Many women use fingers, vibrators or other 'aids' during sex to help them. There is nothing wrong with it. For some women it is easier to use other methods to climax before or after intercourse. It doesn't mean either of you are doing anything wrong.

There are a few women who find changing position, angle, or tempo can affect whether they climax during sex. If you feel like you are getting 'close', you might try slight changes and see that makes a difference. Even if it doesn't, experimenting is fun.
