Call TE. They are VERY helpful - if you give them your measurements, they can probably find a pair of shorts to fit you.

It's like anything else - mass produced clothing is made to fit a standard set of proportions. So just as there are women who fit better on non-WSD bikes, there'll be women who fit better in men's clothing. If tight men's jeans fit you better than women's, then it's likely that men's cycling shorts will fit you better than women's, too. If your hips are very rounded and/or much bigger than your waist, then men's clothing probably won't fit you well. If your femurs are shorter in proportion to the circumference of your hips, then men's shorts may be very long and/or baggy at the leg opening.

The one thing that cycling shorts have different from street clothes is the chamois. Men's sit bones tend to be narrower than women's, so the chamois in men's shorts is narrower in back. If you have wider sit bones, make sure the chamois is wide enough to pad them. As far as the shape of the chamois up front, that's really individual. Molded chamois tend to generally reflect the contours of male and female genitalia, but I have no idea whether that's just marketing or whether it really helps.
