Wow! This question is really good because I've desperately had questions about my own self in this area. I have a SERIOUS phobia which I usually don't refer to it in this way, but it does fit, with male ob/gyns. I DO NOT LIKE IT! I've had a very hard time with this, I don't know if it came from a really traumatic experience I had 5 years ago or what, but it brings back those awful memories for some reason and I feel violated all over again. See I've always had a female and my friends would act like I was crazy, they all prefer men and say it's disgusting to prefer a female! I thought something was wrong with me for being so freaked out by it. It doesn't feel right to me, a man doing my pap smears and such.
Last year when I had surgery (endometriosis and female issues) myOB/GYN was a male and they told me HE needed to do a pap smear himself RIGHT AFTER I'd just had it done by a female which was not my regular ob/gyn anyways and she screwed things up so badly with patients she ended up fired! Anyways, I totally freaked and cried and asked her to please, please understand and let me have a female! She told me it was not possible any where in my area or in chattanooga which is about an hr away where I knew they had to have female OB/GYN'S she laughed and blew it off. So I ended up going for it & had the rest of the day with horrible memories and it just brought up everything from that experience 5 years ago with the rapist. I don't know why, but I've strongly protested against ever letting a male do my health stuff and then I had no choice. It felt awful and most people think I'm stupid for it, but it truly brought really nasty feelings back for me.
Anyways, this male OB/GYN done my surgery and kept telling me NO SEX, NO TAMPONS, NO VAGINAL ANYTHING! I assumed it was because of just the surgery which they went through my stomach right under my belly button. I didn't think much of it and then I found out on my own that he'd stitched my cervix! I think he should've told me that. He wouldn't. I called and asked him why it was stitched, he had no answer.
Every 2 weeks for months before my surgery he wanted to "feel inside" I fucking hated it and didn't understand the reason for it. I mean at least let the nurse who's standing in the same room do it if I'm THAT uncomfortable. I wish it never happened. So yes I totally prefer a female and will NEVER, EVER let a male touch me or look at me again (of course my partner, but that's all!)
I also prefer a female because when I went through all that pain and suffering nearly my entire life, there was no way a male could truly know what I felt or even relate to it and women can. Women can relate to those types of things much more than a male even if the male has 100 degrees, he still can never know what it's like or even close to what it's like. I have a specific female OB/GYN now and actually was supposed to see her for a shot today, but it wasn't possible so I didn't go. I will not see anyone besides her now. I just think women are more able to relate and understand and plus I don't feel it's any man's business to take it upon himself to do things to me knowing I don't want him to. If a woman asks for a female to do those things then the male dr. should take that into consideration and not blow it off.
