UTI🙄🙄🙄

Most of the time when I have sex with my boyfriend I get a uti I always pee after sex and we have protection always but it’s so annoying it would be 2 days after we have sex It’ll be so stinging down there when I go pee and so irritating…. Anyone know any way I can stop this from happening?? I drink a lot of water so I honestly don’t know why I keep getting them it’s a pain in the hole😭🙄🙄
