I feel like this is something that a lot of people do with friends, like a completely platonic friend. But, some times I feel like I'm being a little too open even know my one friend is a chill person I can trust. My guess is it's just social mores or something causing me to feel this way?

This is an area that just completely depends on the relationship--in one friendship there might be no talk of sexual experiences or desires, and in another there might be very open, even graphic, talk about these subjects. If you're wanting to chat with friends, or even just this one friend, about sexual subjects I would suggest directly asking if they are comfortable with/interested in that. If they say yes, than hopefully you can worry less about being "too open." (Although it is also of course helpful to check-in with body language/energy as well.) Because as long as the other person is interested, there is absolutely nothing wrong with talking about sexual subjects with friends! In fact, it can be a great affirming and/or educational experience.

I'd actually love to talk to my friends about that but I've never meant anyone as open, or I just haven't been as open being an introvert. But I think what Alice said fits the bill - just ask! Sometimes we spend so much time wondering what people are thinking when the only way to find out is to ask them. I know I spend too much time trying to read people's minds but I have to realize that I will never know what's going on in someone's head unless they tell me honestly what's up.
