Follow your intuition, dude. You have laid it out fairly clearly here that you think having anal sex with your friend may lead to him having romantic feelings for you, which you are worried would change the dynamic that is working for you now. So my advice is to take this sentiment and share it with your friend. He’s the only one who can give you that reassurance.

This comment is kinda mean. He successfully engaged the audience and even makes them laugh while informing them on his topic. I’m curious to hear what qualifies him as a “bad speaker” in your mind.
