How do I make sure the sex will be good for both of us? /u/silly-mouse-42069 Sex

I (20F) plan on having sex with this guy (23M) I have been chatting with.

My last partner said the first time we had sex it was bad. He wouldn’t dive into why, and I cannot ask him now. We did foreplay, it was really good for me, and I always try to be mindful of my partners. He said it was amazing after that, I just don’t know what I did wrong.

I am very nervous I’ll drive him away if he feels like the sex is bad. I also don’t want to embarrass myself. Any advice would be appreciated. Thanks!
