Peeing After Sex

Any advice on whether or not it's bad to pee after sex if you are TTC. My partner thinks that it's bad and I disagree. I am huge on going to the bathroom afterwards along with drinking a glass of water; I have dealt with UTIs in the past and that is something that I never want to deal with again. It has always stuck with me to do that from the advice from my doctor and that's what I have done for the past 10 years and haven't had any issues since. But now that we are TTC, I don't want to be doing something that is going to hinder our chances.
