I am a woman and would prefer a male ob-gyn even though i have used women (frum too) before and most of them have been QUITE insensitive. That is not to say that there are not frum women or any women ob’s that ARE sensitive or males that are utterly horrible. Generally speaking, MOST (not all) women will agree that men are not only more competent in this area but more sensitive in many cases.
To suggest that men that go into this field have some sinister or perverted motivations is completely ridiculuos and immature. This field is about bringing BABIES into the world, preserving women’s health, treating various ailments… I don’t understand such ignorance masquerading as tznius or whatever. If you want to use a woman ob-gyn … ok. But an ob-gyn that is a male is not a man, but a PHYSICIAN and is trained to view things through the prism of his training, etc.. There are boundaries and most normal people can understand the difference. Of course, there are cases that i won’t elaborate upon where a woman would be further traumatized by a male doctor… not because of the doctor, but because of the woman and her particular experience.
