Depends on the friend and if we've brought up anything like that before. I have two or three good friends I can openly talk about sex and toys to (and have introduced them to Eden!), but I think it really has a lot to do with how comfortable both of us are about venturing into those kind of topics.
I've made a lot of friends in the kink community and I can talk about anything sexual with them. When it comes to friends outside of that it really depends. With some we do discuss sexual stuff but even then, it's only vanilla sex stuff.
I live in a shared home with close friends, everyone is pretty open and comfortable with sex stuff and sex-type things tend to come up decently often, especially since one of the roommates and our good friend who comes over often both work at a local sex shop. We don't talk in detail about our personal experiences or get graphic usually, nothing TOo dirty haha.
I gave a friend of mine a glass dildo I got free from EF and never used. The look on her face was priceless. She was so embarrassed, but she said she'd likely use it but not tell me if she enjoyed it or not because she doesn't talk about such. lol
My best friend is the first person to read all of my blog posts and she often calls me to discuss them lol. I'm really open about it but respect my friends feelings on the topic. I will talk to anyone about sex.
I guess it has to be easily lead into the conversation and seem natural, otherwise it would be weird just to blurt out LETS TALK ABOUT SEX, BABY. But I'm not opposed to the idea at all, and often have in the past.
