Can't say that I've seen an electric one.
In the end, men's are the same as women's, but women are usually more willing to pay a higher price for a pink package.
I love my Gillette Mach 3 Turbo razor. The handle has a nice even weight to it, and the blades are easy to rinse off and keep clean. A clean dry razor will work the best, and last the longest. So keep it out of the shower between shaves, and pat it dry on a towel before storage.
You would think the skin on a face would be way more sensitive than skin on your legs. So if it's good enough for a man's face, wouldn't it be just as good for a woman's legs?
