I fancied a guy for ages but am turned off by this

I have crushed on a guy for ages, and he gets sooooo many girls after him and sleeps with lots of girls.

Finally we started talking and one thing led to another and I was at his house and I gave him a blow job. His penis had the weirdest sweaty gross smell and it turned me off. His penis was also extremely tiny and he couldn’t get it in. I feel totally unaroused. I don’t understand why he’s usually so successful with his sex life
