F19 M20 Date night gone okay?

Long story short, he came to visit last week and stayed the night since he lives about an hour away. We clicked really well, and things progressed physically. The first time, he stayed hard until he finished. After that, we kept going. He got soft, then hard again, but as soon as we actually started trying to have sex, he went soft and couldn’t get hard again. I assumed it was just because he had already finished and couldn’t keep it up.

Then on Valentine’s Day, I saw him again. When I started going down on him, he got really hard and seemed completely ready. But as soon as I got into position to have sex, he went soft again.

Now I’m overthinking it. I’ve never had this issue with any other guy. I know I don’t smell, and everything was clean we had even taken a bath together beforehand. He seems perfectly fine and turned on in every other situation. Right before we were about to have sex, he even whispered that he wanted to put it in, so he was clearly in the mood. I just don’t understand why every time we actually try, he loses his erection.

I’m starting to worry that he’s not sexually attracted to me. But everything else besides the actual penetration part is amazing.
