Yes, No and Maybe lists aren't something we invented.
We might also sometimes find ourselves feeling inclined to only say what we think a partner wants to hear, or only responding to what they bring up rather than putting our own stuff on the table and initiating our own questions. It can feel like being asked what you want to eat at a restaurant without having a menu to even know your options. When sex is newer to us, we may not even have a sense of all there is to talk about. It might be particularly tough to start these conversations if talking about sex openly and out loud is something you've never done. Someone might ask what you do or don't like, or what may or may not be okay with you, and you may find you - or a partner, when they're asked - have a hard time knowing how to respond. Starting deep and honest communication about sex can be daunting, especially in areas which can be more loaded, tricky or where we feel vulnerable. We can't just know or guess what we or others want or need, like or dislike, are or are not okay with: we need to communicate those things and have them communicated to us.
It's the best way to assure everyone is fully and freely consenting and physically and emotionally safe to help sex and sexual relationships be as satisfying, positive and awesome as they can be. Clear, truthful and open communication is a must with partnered sex.
