Sometimes when I'm on the exercise bike at the gym my weiner falls asleep...

It looks like it's a common enough problem that bicycle seat companies are using it (or lack of it) as a selling point for their seats...

Are You Exposing Yourself To Unseen Dangers By Riding A Bicycle? Derri-air Can Help

I have a bike at home and I get it as well.

I like it, the only piece of equipment I use regularly.

I used to get the same sensation from climbing rope at school back in the day.

It made me overcome my fear of heights.

Sigh. I'm fairly positive now after reading all these replies, this is some sort of very clever subliminal Viagra advertisement. Or, yer all .

LOL This is so funny because I had the same thing as well after long exercise bike sessions.... It feels really numb and fuzzy and kind of "useless" for about 20 minutes.... It does feel kind of disturbing, especially the first time it happened... I'm about to run a google search on it which may be interesting..

Thank god there is no pins and needles afterwards!

Oh there are mild pins and needles sensations afterwards. It's... awkward.

Bike seats are just uncomfortable. Use the cross trainer.

I don't use the bike very often, but I don't like to do the same thing over and over again. I have four different types of cardio workouts: the eliptical, running, the rowing machine, and the cock-numbing-then-tingling bike.

It is normal you get use to it and it will affect you permanently. So do worry.

It is a strange feeling. But kind of nice when the blood rushes back in after.
