My first hook up w a guy

Hello, I just recently broke up with my girlfriend. I am getting a lot of curious thoughts so I downloaded Grindr. I’ve been going back and forth with this really hot guy (29) I’m (22). I told him it was my first time with a guy & he has been a mix of dominate & also listened to me. He said he’s taken a lot of younger guys virginities. We planned to have sex next Friday. I’m scared I’m going to back out last minute because I don’t know him and I will have to go into center city to his apartment and he’s also big so it kind of scares me. I need tips because I also feel like it’s super transactional which is hot but also makes me scared I’ll feel really bad about myself after. Thoughts?
