I woke up this morning, and I masturbated, first time nothing came out when I ejaculated, and I got worried. Did it a second time a little amount of semen came out, did it a third time cuz I was worried, and again just a little amount came out (3-4 drops which isn't usually the case. I read about a condition where the semen would go into the bladder which made me worried since I want to have kids, however the sites I read about this condition through all say that it happens either after a a surgery, or due to diabetes, or due to some medications, and i've never done a surgery, I don't have diabetes, and im not taking medications, what could be the cause of this dry ejaculation?
