Rebound Sex?

I recently went through a break up. Not something I want to go into a lot of detail with right now.

Not long after, I received a message from a guy I dated briefly in college. He was great - literally in every way. The reason we didn’t last was because I lived in DC (USA) and he was living in Ireland at the time. We saw each other a couple times but the distance was really hard - especially in college. He moved to London a couple years ago and I recently relocated to Boston. Super quick trip over.

Just yesterday he told me I should come out and visit. I have no issue going but I’m also kind of nervous. I 100% know that we would have mind-blowing sex like we used to - and probably even better now - but I don’t want him to be a “rebound”.

What do y’all think? Yay or nay on going for a week or so?
