I cried during s*x with my bf yesterday. I have no idea why

Title says it all lol. Has this happened to anyone else? It didn’t hurt, he didn’t force me to (I initiated it) I just randomly started crying 😿. Now I think he’s scared that he hurt me however I told him he didn’t, he’s just being caring.

I’ll look at replies in the morning. Thank you for anyone who comments :))
