I would bet a large amount of money that within our lifetimes there will be a female doctor, a black doctor, an LGBT doctor AND a ginger doctor.Maybe they'll mush it all together, make the next doctor a black woman with freckles, red hair and a taste for other ladies.

If we get a female Doctor, then a lesbian Doctor wouldn't be a huge leap away - assuming she still has primarily female companions. Not hard to make it happen.
