I do not think that anyone should be obligated to answer that. I think partners should respect if the other person wants to disclose it or not, but if one person really has to know, they should explain why it is so important to them to know. If it is disclosed I think it should be done early. I have never been asked that in any prior relationships, nor have I ever asked because it was not important to me (the person is in a relationship with me now and that was more important to me at the time), but in my current relationship, my boyfriend demanded to know how many and he would not let up, so I told him (and it is a very low number) and I also told him that I did not want to know his. He was annoyed that I did not want to know his. He then proceeded to grill me about their sizes, length, and girth in comparison to his. It made me feel so uncomfortable and it hurt me a lot because one ex-boyfriend in particular hurt me badly and I did not like recalling him at all, but I was pretty much forced to tell all. I also felt in a way that disclosing such detail was a violation to my exes’ privacy. It really hurt me that my boyfriend saw how much this stressed me, yet for whatever reason, he still demanded to know every last detail. Is that normal?
