I've personally had issues over my own past and became hesitant to tell a partner honestly if they asked and have lied to avoid my own embarassment. I have been honest with only a handful of women, a few of whom walked out immediately, a few got quiet and contemplative, and one didn't seem to mind. Keep in mind, I'm not boastful of it, it was a bad time in my life and soon quit sleeping around and got engaged. Since the engagement was broken off and she died, I'm very scared of having to tell another girl.
So I ask you (men and women), would you want to know if your partner had been around the block waaaaaaay more than you have? If so, what makes you want to know? How would it make you feel? Would you take the time to understand why the person had so many (insecurity etc)?
Just looking for opinions. Lets assume you wouldn't run into one of their many partners or if you did they were discrete enough to not mention anything ever happening.
