I'm 23 years old and i am facing a problem of numb penis, the tip of the penis feels like it's almost dead, i can't feel anything over there at all. I feel a little pain in the area between anus and balls. Erection and ejaculation are totally normal. When i try to stretch penis internally (without actually touching it, applying internal pressure similar what we do while urinating) i dont feel anything around the tip, rather i feel across the area between anus and scrotum. I masturbate 5-6 times a day. Last week while having sex with my partner my penis bended accidentally. I'm too tensed what should i do?
