What you described doesn't sound that unusual to me at all. I tend to get flighty during sex and spend the whole time trying to ground myself or dissociating. All senses are heightened and I find it is extremely irritating and difficult to cope with. This sounds a bit like what your guy described when he said it almost feels too tight. I have never orgasmed with a partner and I'm not sure I could even get to that stage even if I wanted to. I want to dull sensations not increase them. For me it probably is about staying in control. But I still get enjoyment from the closeness of being together. There is also medications and medical related causes to consider. Maybe he just wanted to hold out so it would last longer and be more special. I wouldn't take it personally. If he wasnt attracted to you he wouldn't have been there engaging in hours of sex with you.
