I am 19 years old. My right testicle got swollen for a week but now it has gone down but I still have a dull pain there. When I ejaculate I get a burning sensation/irritation in my urethra for a few hours after and if I urinate it feels better for a minute. When I walk down the stairs or if I jump my right testicle hurts. And now even the pubic bone area (bellow by belly button) to the right hurts as well when I touch it. Ive had this problem before but it went away after a week but this time ive had it for two weeks already. Does anyone know what it could be. I have a theory I think it bacterial infection cause by masturbating while sweaty/dirty but I dont know.

Ps I know its not an std because I dont have sex and the last time I received a blow job was 5months ago.
