i just realized something i had never....

[fusnik11]

realized before....

i dated a girl who taught a cycling class...

when she would lay on me and sit up her butt was so freaking hard. i just realized it was probably because of spinning and her riding her bike wasnt it?

[MikeWaters]

what was hard?

[fusnik11]

her backside....

basically the area where she would be sitting down on a bike....

do you riders create some sort of large callous there?

[creekster]

so I can keep my butt sized callous in good shape.

I can crack a walnut . . . well, you get the idea.

Speaking of back sides, just what happens to those old guys butts that can't hold their pants up anymore.

We all know the guy, pot belly and no butt what so ever. Infact it's concaved back there instead of convexed.

And just how old do you have to be to have that particular phenomonon happen?

One of the things we have to look forward too. Women get saggy boobs and well, we get a disappearing ass.
