Motorcycles Can Be Dangerous For Your Sex Life.

We all know that motorcycles are dangerous. But for your sex life too? A study carried out by doctors in Japan has revealed men that ride motorcycles are at risk of impotence and urinary problems because the vibrations of the engine damage nerves in their penises. The survey of more than 230 motorcyclists who rode their bikes for about 3 hours every weekend found almost 70% had problems gaining an erection or emptying their bladders. The reasons: 1-motorcycle seat undue pressure on the perineum, that unknown area between the anus and the scrotum. The pressure can restrict blood flow. 2- vibrations from the engine caused a decrease in two growth hormones in the bladder and prostate related to bladder relaxation. I didn’t know that such a number of bikers had trouble getting one up. I would be interested what the same survey would find out about the incidence of vibrations on female riders.

    Has nothing to do with motorcycles
    It’s a cultural problem, specific to Japan.

    Mr T. You are so funny (not on purpose!). Since when nerves, bladder and prostate damage is qualified as “Cultural”. Your sex must be pretty bad…

    From the female perspective ……………the worst part about the vibration issue is finding a route going to and from home both directions up hill……….I KICKSTART MY VIBRATOR !

    The study in Japan means that the riders were most likely to be riding “sport” style bikes where you have to lean forward so the riding position is very different from the US style cruiser where you sit upright or lean back slightly.

    I checked sitting on my home built chopper and no pressure was being put on the area talked about on this survey. So I think the headline is a little misleading (much the same headline appeared in the Sydney Morning Herald last weekend). It should probably say “sport bike riders” rather than motorcycle riders. As for the vibration, I don’t know, it has not effected me and as far as I know it has not effected any of my riding buddies…but hey we are all 50 or there abouts so we all have enlarging prostrates.

    I’ll cover my perineum with pershing blue and see what kind of pattern I leave on the seat….

    You have to wonder about how this study was conducted. I guess the guys with the giant sheep carcasses on their seats are not experiencing this problem.

    Stay off the rice bikes.

    Wow ! Thanks Cyril, now I know the correct medical term for ” Taint” its perineum! cool, and as for the rest, my female passengers ( for some reason ) I think the vibrations make them want to “protect” my guys by hand. LOL

    Stephen’s comment to me has always made sense. And as far as sex life, right. I ride my 3 boys ride and I have 8 grandkids. And I wake up every morning think I’m bad!

    Certainly interesting. I’ll stick to my classic Indians as it doesn’t seem to create the same issues.
    Quite a hard subject to discuss and keep it proper isn’t it

    Cyril! Stop the crazy talk! You’re scarin’ me!
    Interestingly enough, Terry Roorda did a piece in Thunder Press a while ago and had some insights on a similar phenomenon, more to do with numbness to the area if memory serves. Very funny piece, though a wee bit scary – for boy riders. But us girls, we just ride around all day, goin’ fast in second gear! Sorry Mike, I think I just crossed that proper line, but it had to be said!
    Happy Thanksgiving all, and Cyril, thanks for keeping us informed and smiling!

    Pepper , you just brought a smile to my face ! And its a bit “red” after the “we just ride around all day, goin’ fast in second gear! ” comment. LOL

    I do ride one of them-there rice flavored sport bikes (Honda CBR400RR) and I hafta say it’s actually got more padding than the bumstop cafe racer seat on my vintage Benelli. Maybe it is a cultural thing after all, those brits on their cafe racers never seemed to complain about not being able to get it up, but maybe they just didn’t want to talk about it! Ditto for all the midwest farmers riding unpadded steel seats on their John Deere tractors.

    “… But us girls, we just ride around all day, goin’ fast in second gear!…”


    Put some “Pepper” on that ” perineum.”
    Bet-ca that “numbness” vanishes in a hurry………… 🙂
