Date-A-Doc

Go ahead; make mom happy and log on to Date-a-Doc. Forty percent of users here are doctors, with an average age of 37. You'll also find hospital administrators, academics and a handful of Florence Nightingales. Descriptions detail users' educational history, as well as things like body type and favorite foods--from the British-born Ph.D into body building to the M.D. in D.C. with a penchant for French cooking. The site recently implemented a fee paying-based system. It's still no fee to post an personal, but that'll just get you into the waiting room. For further contact with the docs, you'll be billed $18.95 per mnth.

A new feature lets you see which users are checking you out.

While the site has a general chat room, there is no one-on-one option.
