UTI's from Sex 😢

Does anyone else get UTI's from having sex? I get them most times after having sex and really wish I could do something about it. I'm extremely frustrated with these stupid things. I've tried everything to avoid them, from 100% cranberry juice daily, peeing before and after sex, water, water, water and I cannot seem to avoid them. I went to see a urologist and he has put me on antibiotics and I am to take one right after sex EVERY TIME! 🙁 Last I week took the last pill and haven't had the chance to call for a refill and guess what... I've got a UTI 😢.
