Not really, I'm 20 and will openly discuss my sex life with my mother... if I had one.
We're completely capable of being mature about things like sex and porn, and don't let petty "YOU SHOULDN'T TALK ABOUT SUCH THINGS" thoughts cross our minds. It's easier to just accept that it's natural and instead of having it pent up you have someone to talk to about it

.
Don't get me wrong, I don't want to hear details, but if it comes up in a conversation, I don't go all jewish on them. lol
