Is this normal after sex? 😩

So my husband and I have been married for almost a year and every time we have sex, I get a UTI (Urinary Track Infection). And when I say every time, I literally mean every single time. It's come to the point where sex isn't worth it for me anymore because of how much pain I have to go through when I'm peeing. It BUUUUURNS so insanely bad. Sometimes my husband tells me he doesn't want to have sex because he doesn't want to put me in pain. I've got through tons of pills to make the burning go away. Anyways, here's the thing I don't understand. My husband and I both follow a religion where we are suppose to clean yourself throughly 5 times a day down there so that is exactly what we do, we are both very hygienic people and take care of ourselves well, yet we still have this problem. We clean ourselves before AND after sex as well, yet nothing!

I'm just very confused, and frustrated at this point. I really want some answers. What's wrong? Am I missing something here? Is this normal? Should I get this problem checkout by a doctor? Please let me know any advice you have because I'm very upset! ☹️

UPDATE: Yes, we both pee after sex. And if we have to pee before, we clean ourselves before doing anything!

UPDATE UPDATE: I know a lot of people are commenting that it's unhealthy to clean yourself that many times a day, but what I meant by 5 times a day is that we only use water. That's only to get rid of bad bacteria and odor. You have to wash your butt after you poop and wash your privates after you pee! 😆 That's unsanitary if you don't. Is that still considered over cleaning? 🤔
