I've been having sex for the past 3 years and have never once had an orgasm. I've been with 4 guys but mainly 1 for the 2 1/2 years. It's not that I don't enjoy it, I just can't ever even get close... any suggestions??

In all seriousness. My wife had the same problem. Still does unless she uses a toy.
She read that this is a common problem with women, so you are no alone.

Try a massager.

Masturbate.

If YOU don't know what pleases you, how can THEY possibly know?

It seems to me that you are lacking passion for whatever reason.

Sexuality is complicated, and many of the sexually charged situations that turn you on are buried in your head, put there when you were a child. Perhaps, you had religious upbringing that had a negative effect on your feelings about your own sexual feelings.

Firstly, you have to find out what thoughts turns you on... really turns you on, not what is supposed to turn you on. :)

Don't worry, everyone has strong sexuality; it's built in! Women have to do a lot of work getting rid of negative societal influences and religious and social propaganda in order to be free.

That is a common problem with girls.
Provided you are heterosexual, menstruating regularly and not taking any medications, the two most common causes are:
1. He is not doing it well
2. You cannot let go (too shy, too tense, or too perfectionist)
Good Luck
