About 3 weeks ago, after vigorous masturbation my penis swelled a lot. There was no pain, no loss of sensation/feeling, no blood, just swelling, and the next day the swelling went down significantly. After about 5 days rest, over the following week, I had sex twice and masturbated about twice (never mroe than once on the same day). Now I have abstained for 10 days, and there seems to still be a touch of swelling, and some minor tingling in the nerve area (only after i have an erection or use the bathroom). Again, everything seems to be fine (erections are good, no bruising/blood/pain/etc).
Is this going to heal up soon or should I see a doctor?
