I used to have an enormous crush on Dr. Kerry Weaver from ER, lol! Actually, I think I went through most of the female doctors in that show - Dr. Lewis, Dr. Corday - oh, my Goodness. Dr. Corday.
Lately, rather bizarrely, Dr. House has wheedled his way into my affections... Perhaps I like Doctors who use canes...

It's an interesting thought... Do you think that sometimes perhaps people who long to change their bodies develop fascinations with people who can make that possible? Though not all Doctors are plastic surgeons, I suppose, lol. For me, the fascination has always been the implication of vast knowledge in an area that's totally alien to me - I'm completely artsy and entirely unscientific - and massive focus on physicality. Also, that weird combination of formality and intimacy that's involved in a Doctor's appointment - the fact that they're touching you and examining you in places that only a lover would otherwise touch, but they're doing it in an allegedly completely non-sexual context. Oh, and the paraphernalia, lol. Gloves, stethoscopes, tourniquets...
And with Dr. Weaver and Dr. House, they also have their own physical difficulties - their own pain to deal with. So that adds a whole new dimension to the thing.
Either that, or I just fancy Laura Innes and Hugh Laurie.
