Peeing pre or post sex?

Am I like the only one who doesn't get a UTI from either peeing right before or right after sex? I see all these posts about making sure you pee right before you have sex or right after you have sex because it will cause a UTI. I haven't had a UTI in forever and I have sex 5-7times a week and I never pee right before sex and I usually have to pee directly after sex. Am I just a freak of nature? Does everyone have this UTI problem?
