You are only addressing touching patients. There is a big difference between performing your duties as a physician (which of course includes making physical contact with other people) and being touched in ways that may not seem appropriate to you.
If a school doesn't mind setting up OMM labs in a way that avoids contact that would seem uncomfortable, I don't see why it shouldn't be done. I'm proud that TouroCOM does this.
How are your other classmates supposed to learn? Sorry, but if you haven't noticed the male and female bodies are quite different. I don't think I would want a doctor examining me who had never dealt with a female patient before and if the OP is put into groups that are only females touching females or males touching males, they are missing out on important differences.
from an osteopathic point of view... they really arent. The difference between male and female anatomy fall into two categories: A) Fat distribution and B) things that should make no difference if you can palpate well.
If youre a female who wishes to only be touched by other females you wont lose a thing. If the argument is that only being palpated by females means you'll likely only palpate females (not necessarily true as even the most conservative people will jump to anyone who has an interesting finding to feel it. but *mostly* true), then I posit to you this: will they really be thrown for a loop by a smaller carrying angle or a thinner innominate? I think these are things we know to expect and dont need to palpate male hips if we've palpated the female hip 100 times. Its known that its thinner. You wont freak out if you palpate your first male patient and the width is 15% thinner than you'd expect for a female. As for fat distribution: no one palpates fat (or if they do, they are palpating through it).
In an ideal world everyone touches everyone. But ideal world is not our world. People have rules they must live by. My understanding is most of them fall into the "I can touch whatever I have to for my profession, but I'd prefer to not have "x" touch me". Thats not a big deal and its good to have established criteria to work around it and not hinder anyone's education.
