Why bikes? you suspiciously ask.
After riding your bike or going to spin class you get off your bike and you've probably noticed that you're a bit numb in the bicycle seat area, i.e. crotch.
Traditional bike seats, the kind with a narrow rear and pointy nose, could lead to or play a role in sexual impotence, sadly.
In fact, there was a study by Boston University in Italy found that the more a person rides, the greater the risk of impotence or loss of libido -- seriously! And, mountain bikers experience 'saddle-related trauma' as well.
Those crafty bicycle seats mostly affect men's love lives, however, women can have similar issues to men, i.e. low sex-drive or sexual dysfunction.
Whew! Before you start crying and bringing your bike to those expensive counselor appointments or even posting your brand new bike on Craigslist, it's been suggested to buy a new seat for your bike that's specifically designed to protect your privates.
Or, you could try a different position while riding your bike.
Or, you could just continue riding your bike, like you do, with a numb crotch, and become a Nun or Monk. I hear they have some great internships!
