Ok so I love my girlfriend very much just that she's slept with 14 guys before me... And it really really hurts because I know most of them... Please someone tell me what I should do...

To be blunt: You either accept that her past is her past and leave it alone or you let her go and find someone whose past is more acceptable to you.

How long have you been dating? Why did you get involved with her to begin with? Did you know about her past when you began dating her? Did you fall in love with the whole female (body, mind, past present and future) or just the parts you can easily accept?

I am a bit concerned when you say her past hurts you. How?

Anything that you two do together is unique to you as a couple whether it has to do with sex or going to a movie.

You can either leave or get over it.

How old are you both?

14 past lovers? As in she's had sex with them all?

Whilst I accept its her business, however, you will need to find out if she used protection, and if not has she been checked out for STDs, and get checked yourself if you plan on sticking around.

Like other have said, you need to move past her past or move on. Something like this can eat at you and you can end taking it out on her in ways you would deny now but it can happen.

Her past sexual behavior bothers you. Did it bother you before you slept with her?

If you plan on staying with her, it might be a good plan for you to get some personal counseling. I can see problems coming up. For example, if you two have an argument - are you going to throw her past in her face?

You did not state your respective ages. Maybe neither one of you is mature enough for this relationship.

Which ever way this relationships goes, the best of all to you both.

"If you can't take the heat, then get out of the kitchen."

You can't change her past, it's always going to be there. If you can't accept it, then find someone else. Don't need to torture yourself.
