i masturbate a lot and I have sex sometimes too but I notice that whenever I go to poop, white substance comes out of my penis several times before urine, it happens all the time I go to poop and it's getting me worried so I decided to see a doctor and I was diagnosed of staphylococcus and I was given some antibiotics which I just started taken. And I also noticed that's I can't last more than 2 minutes while having sex before ejaculating.... I'm really bothered about this and I need help asap
