If you are talking about sex, and your friend says something like “I have never heard of that!”, don’t shame them, educate them!
I have heard people shame their friends for not knowing everything they know about sex and relationships. This kind of behavior leads to dangerous and ill-informed experiences that can end badly.
There is no shame in asking questions about bodies, sex, experiences, relationships, kinks, or fetishes. It’s totally ok to question things, and to not know everything! Everyone has to learn at some point, and that’s ok!
At the same time, if you are not read to learn about these things and don’t plan to participate in anything anytime soon, it’s ok to excuse yourself from a conversation, or to change the subject. Don’t pressure anyone into talking about sex if they don’t want to!
This is just a short PSA because I see and hear this happen so often!
Be nice to other people who don’t know everything you know, take that chance to teach them or to give them resources to learn.
