Disclosing sexual partners
I am a 21-year-old male who lives with his 22-year-old girlfriend who happens to be far more sexually experienced than I. I often find myself wondering how many partners she has had, but when ever I bring it up she becomes extremely defensive and tells me that it is,"Non of my business." I disagree, mostly because we are so close and have even discussed marriage. I am posting this because I would like to know if it is normal for couples to disclose their "Numbers?"
