I'm not attracted to him...

I know this sounds really mean, and I don't want any rude feedback but I need advice. I've been on a few dates with this guy, he's 10 years older than me and honestly the sweetest guy I've ever met. He treats me really well, he's a gentlemen and he never pressures me to do anything (unlike my previous boyfriend). But at the same time, I have needs! Lol, I'm horny and I want to have sex. I don't want it to be anybody random, I would like to give myself to him but everytime I try, I can't get into it. He's just not attractive to me for some reason, I just love his personality. Am I being ridiculous? Should I just do it anyways? Or move on? Please help, I feel really bad about this but I can't help who I am attracted to.
