Your p-spot is swollen because you worked it too hard. The p-spot is responsible for urinating and also nutting so that's why the stuffty 'needs to pee' sensation is happening despite nothing being in your bladder. It'll go away eventually. Take a bath or something.
This is also why it's a good idea to urinate before you masturbate, the p-spot will need time to relax after an climax or it will become fatigued.
you have a UTI. always try to pee after you climax, otherwise this happens.
Wouldn't call it a UTI. Might have the symptoms of a UTI but it's probably not a UTI. I get this stuff all the time.
