well, let's put it this way. Nothing impresses my husband more than to see a beautiful woman on a bike in her jersey and shorts with her feminine muscles glowing, etc, etc.
He can definitely tell the difference between guys on bikes and gals on bikes.
A healthy woman is a feminine woman. It doesn't take hairstyles, makeup
or stiletto heels to make a woman.
In fact, my DH who used to whine that i didn't have shapely legs like gals in those stilettos can now see the diff between legs that have walked in stillettos and legs that have gotten strong through biking and he prefers the biker legs.
So if i were you, i wouldn't worry too much about the bike ruining your
feminine nature, it will enhance it!
