I've recently been riding my bike down a bike path near my house and go a few miles, but on two occasions, by the time I get back to my house and get off the bike, I've noticed that the tip of my penis becomes super-sensitive and the feeling lasts for several minutes. The sensation is so intense (it somewhat feels good) it can almost be unbearable. I couldn't even sit the first time this happened because it only made the sensation stronger.
I thought maybe it had something to do with the underwear I was wearing because the first time I wore boxers and hypothesized that maybe my goods were moving around too much. I rode another time wearing briefs to hold everything in place and the same thing happened. I have more or less come to the conclusion that this is not caused by my penis rubbing against my clothing.
I don't have an erection when this happens, and I masturbated right after this happened the same time thinking maybe that might help, but the sensation wasn't really sexual in nature.
The only other thing I can think of is that maybe a nerve or blood vessel got pinched while sitting on the bike seat.
Has anyone experienced this or can explain what is happening?
