Has anyone ever had a UTI?

So right now I have a UTI, (my fiancé was in town and we pretty much went balls to the wall all over each other, he's also a little big for me in that area LOL) anyways, I've kinda been staying at least 10 feet from the bathroom at all times waiting for these antibiotics to kick in haha, so has anyone else had one of these before? I'm just curious because I'm kind of freaking out right now because I just want to feel better😭😭 also I think it sucks, is there anyway to have a lot of sex without having to worry about this again ?
