Raf, see a doctor ASAP. Napalm and dude napalm commented on, stop jerkin' yer gherkin. Believe it or not, that really does help. You've gotten used to what you do and need a break. You'll be minute men in no time. ;P

Might be the sudden shock. I smacked my head pretty bad in a plane but it cleared up after about a half hour. Definitely see a doc if it lingers. Hope you feel better soon.

That's not how it works for me but then again when I masturbate by myself it's a waste of my time so I don't try to last. On that note, you have a boner, you're horny, you have a pair of hands, I think you can figure out what to do to fix the problem

For some reason, this comes to mind. https://pbs.twimg.com/media/CL-ZoywWcAAzr8q.jpg

@rafaelsanzio I agree with yaasshat. I'd go to a doctor. What you're describing reminds me of when I hit my head so hard that I got a mild concussion.
