Peeing after sex

If I pee immediately after sex, will it hurt my chances of getting pregnant? I've had UTI a couple of times in the past until the doc told me I needed to pee after sex then I had the habit of doing so. My DH is so worried and after each BD, he always insists on me going to pee to prevent another UTI but I just want to lay down on the bed because I'm afraid going to pee will affect my chances! It's my 3rd cycle TTC and I keep blaming myself for going to pee after sex!
