Right, this is one of them "I've got a mate" questions......but this really is a genuine question a mate in work has asked me today. He started cycling a few weeks before me. He's pretty fit and healthy, but has told me about this odd problem he's having. My initial thinking was given, and he's said it's a possibility but didn't know where to go or who to ask, so I said I'd ask on here. Basically, he does a 6 mile route on a road bike with a normal seat which he says puts pressure on his grundle (the definition of grundle, just incase anyone doesn't know is Noun grundle (plural grundles) (US, slang) The area between anus and scrotum in a male) When he's finished, he says it feels like he can't walk properly, and feels like he needs a wee. His groin area is extremely sensitive, but his dingaling doesn't change in size....but gets what he could only describe as a pre hard on feeling. Then after a few minutes, all these feelings disappear and then he's fine. I suggested that maybe, seeing as the seat presses against his grundle, maybe his prostate is getting some kind of a massage and this is causeing these feelings. Has anyone got any ideas at all on this?
