You know I sort of have a bone to pick with this . . .
In college, I dated a man who had been with two women. He asked how many people I had been with and so I gave him my number and he said he couldn't be with me because I was more experienced than he was. I swore from that point forward I would never give out my number again. I will say that I have been tested for STDs and have always been clean, I will say that I have been faithful to every man I have been involved with, but I refuse to answer "how many?"
There's a serious double standard in our society - men can sleep with as many girls as they want and they are studs, a girl with the same number of lovers is a slut.
If you can't get over her past - then you need to break it off, because somewhere out there, there is someone who wants to care about this girl for the person that she is not a number that is part of her past.
In the future my advice would be ask the questions that you need to know the answers to in order to protect yourself but don't ask questions that you really don't need to know the answer to - does that number change WHO she is or what you like about her? No, but knowing about the experiences she has had may very well keep you from ever being able to really trust your relationship and that is unfortunate.
