UTI’s no matter what I do 😩

For as long as Iv been having sex Iv been getting UTI’s, I get one everytime I have sex even though I pee straight after. I’m always clean, Iv also had UTI’s when Iv not had sex but been fingered or whatever. Iv had about 10 UTI’s this year and I just want to know if any of you have any ways I can stop getting them 😩 so tired of it. Nothing I do stops me getting them 🙄
