Umm, I have lots of male friends. Moreso than female actually.
Aside from the odd off colour joke told in my presence, I would tend not to talk to those friends about sex (in a general sense) nor they to me. (I'm not talking about jokes, news stories or anything - that's fine - but 'have you ever tried rimming?' - not fine
)
We share many things, but in a heterosexual encounter, we don't really share the same experience, so they can't really empathise. I certainly don't talk to any friends who know DP about our sex life. I would really rather they didn't blush beetroot and stare at the socks next time we all have lunch 
On the other hand if it was 'oh so and so - I slept with him at uni and he kept his lucky socks on' I wouldn't be bothered.
In a happy long term relationship, I'm not sure why you'd be trading tales with a mate of any gender about your previous sexual encounters, unless you've had a particularly colourful sex life, or an an octogenarian reminiscing about lost youth...
