"whore" = gets paid for sex
Is that what you mean? Or do you mean that as a free adult male he explored his physical and emotional boundaries in a sexual way with a number of different men?
You don't know (or didn't share with us) his growing up experiences or psycho-sexual background. Maybe he was raised in a hippie commune where traditionally prudish American attitudes about partnering, intimacy, and sex were not part of his upbringing. Perhaps he was abused and uses sex as a sexual mental salve. Or perhaps he feels like he is a grown man who is in charge of his body and what he does with it is his choice. If he does it in way that isn't malicious, is safe, and treats the other person or people with respect, what's the problem?
Sounds like he should think twice before dating such a close-minded and judgmental person. Your issues with his past sexual life are just that...your issues. Let's start a thread about that.
Sorry to be so mean...I just am offended by these old-fashioned, unhealthy, hetero-normative attitudes towards sex and intimacy. It's 2010...we can enjoy our bodies...that's why we have them
