<human>: My female coworker constantly talks about her sex life. She has a lot of partners (not judging) and frequently tells me unsolicited if she slept with someone over the weekend -- sometimes in explicit detail (the size of her partners' equipment, how it was, sometimes what they did, etc.). We're 'buddies' but I wouldn't say we're super close friends.

I'm genuinely curious -- Do any of you do this? Do you know anyone that does? Any insight into what reason(s) - if any - one has for bringing this topic up like this? It doesn't bother me; it's just different than how I handle myself - I just wouldn't start such a conversation with an opposite-sex-coworker about intimate sexual details. I guess I'm a bit more of a closed book (but not a prude) so it's a bit of a foreign dynamic to me. 

Some additional background: She always tells me she just "likes sex" and "is really a guy" because she likes a lot of sex, so maybe it's as simple as: she just likes talking about sex. She also tells me when she parties too hard or does drugs. She's pretty social and likes to chit chat with everyone. She may have similar conversations with other co-workers, but I don't think in quite the detail regarding the sex. I'm not interested in her, but if this is some kind of flirting or something, I don't want to implicitly lead her on by listening.

Can you condense the text into three sentences or less?
<bot>: Female coworker often details her sex life; anyone have a cross-gender, coworker/non-dating relationship like this?
