Oral Sex

Hello. I’ve had UTIs twice before possible from either oral sex or fingering. Anyways, as of lately I’ve noticed that everytime my boyfriend leaves my house, the next few days are kinda of hell for me even if I don’t have an UTI (I think).

Everytime I pee, at the end I feel like peeing a lil more and that bit feels really bad. I then feel like peeing again after a few minutes but I don’t actually pee anything. At this point it feels a lil ticklish really. I think I should mention that the first day (after he immediately leaves the house) my vaginal area does hurt a lil when I use the water jet. I’m confused whether this is an UTI and don’t know what to do ?
