I don't like the term and obviously it's down to individual choice how many people anyone sleeps with
. That said, I personally don't imagine it's a particularly fulfilling existence, but each to their own. It's not really about numbers, either, I just don't find the idea of rubbing off against a stranger appealing.
I also don't think it's even 100% true any more that women are judged for it and men aren't... there are plenty of women who would be put off by guys having a huge list of sexual "conquests".
