I only talk about anal with my partners.
First of all, I would never talk about sex with my family; that's too awkward.
Secondly, majority of friends and family would only tease me (relentlessly) or lecture about safe sex.
Sometimes I wish I could talk about anal with friends, but somethings are best kept in the dark, at least for now.
By the way, the teasing wouldn't necessarily offend me all the time, but it would just get tiresome and annoying. Kind of like how I have heard hundreds and hundreds of jokes about my Asian background. It gets old. Fast.
