I, in general, prefer male caregivers. I've always had some difficulty connecting easily with other women, but also because I've never had a female caregiver who didn't suck.
I've needed to go to a gyn specialist since I was 20, for endo and ovarian cysts, and every female gyn I've ever been to refused to freakin' listen to me. The guys I've been to were open and understanding, but the women made up their minds about what was wrong with me and how it should be treated, and wouldn't listen to me at all (I was almost always right, too).
My mum says the same thing- she had horrible morning sickness during her pregnancies, all nine months. The women she dealt with were all of the "*I* didn't experience this, so you must be making it up" variety.
Now, I think dealing with a midwife would be better generally than dealing with an OB/GYN. I would be more likely to even consider seeing a female midwife (I pretty much won't see female OB/GYN's anymore), but I sure as hell wouldn't avoid a male mw based solely on his gender.
Then again, I've always felt like I was shut out of this whole "women's mysteries" and "feminine energy" thing, so maybe I'm just missing something.
