About two weeks ago, I was riding a gym bike for 20 minutes, and when I got off, I felt my penis go numb. From hindsight, I can now notice that my posture on the bike was completely wrong, as I was sitting for a good 12 minutes with my weight pressed on the perineum. The numbness passed after a few hours, but a hard flaccid penis followed, as well as erectile dysfunction. This is gradually getting better, as my penis is some times returning to its normal texture and my ED has improved.
But a few days ago, I noticed that I could see new veins appearing on the shaft below the foreskin. I read that this can be because of puberty (I am an 18-year old, by the way). Also, I'm experiencing frequent urination during the evening (which has also been improving).
Does somebody know exactly what I'm suffering from? I think it could be something to do with the Pelvic Floor. Any thoughts? I'd also like to add that I've never felt any pain, except possibly some slight pain the moment my penis went numb after riding the bike.
