Many women ride bikes around here and they are not lesbian.
I ride when I can get a friend to loan me theirs for a spin through the country. Very relaxing and liberating.
Except when my brother would put be on the back of his, ride out into the pasture and tease the bull. Once he slowed down slow enough for the enraged animial to sling snot all down my back. I thought that was close enough.
I suspect the lesbian faction is just trying to "validate themselves".....again.
