Please tell me I'm not alone!!!

I need help ladies so I don't feel so alone about this! Ever since I lost my virginity (about 4 months ago) I have gotten multiple UTIs and even one didn't get treated properly and ended with a visit to the ER because the infection spread to my kidneys and my body went into shock. Since then I've done everything the doctors have said to avoid a UTI (like going to the bathroom after sex) and I still get one every few weeks! Has this happened to anyone else??? 😩
