Search Results: leaving after sex

This is really long so if you stick through, thanks.

This guy I met a few years ago recently messaged me on social media. We talked for like a week everyday all day and a few days in he asked me for a date and I said yes. Fast forward to the end of the week, we had our date. We went to lunch and a movie. It wasn't as awkward as I had imagined. Our conversation was good and a lot of our morals matched up. He kind of asked me if I wanted to do something else or bail if the date is going bad, and I said sure. So we decided to go to the movies. At the movies I started to get really awkward and I just felt uncomfortable. About half through the movie, we finally held hands. It was a little awkward but I didn't hate it, it was kind of sweet. Anyway after the movie we hugged and he said we'll do something again. And I kind of just nooded and smiled.

I honestly thought he is a great guy and he seemed like total marriage material. he's so smart and has his shit together.. But, I didn't feel very sexually attracted to him. I mean I did, but I felt that I would never have sex with him. And I feel like a terrible, superficial person for feeling like that.

So he later that same day texted me and asked if I wanted to go on second date but would understand if I didn't. So I rejected him in a polite way. And wished him well.

The problem is that I now wish I didn't reject him and would've given him another chance to see it any attraction would build.. I just didn't feel right after leaving the date. Like not how I should feel after a date. Like my mind is telling me he's great and I won't find another guy like him but my emotions are saying you know it wouldn't work out because of the attraction. I also feel like I'm not good enough for him, I felt intimidated.

Did I do the right thing? If I didn't, is there a way I could go back and unreject him? Or did I burn the bridge too bad? Or completely?
I know this was very long, so thanks if you stuck through.
