I understand that I left out "with men" in the last sentence. My bad. That last part should have read "Women, whether straight or gay do not serve in all of the same units, and certainly don't share living spaces with men
, and never have."
However, when you are talking about combat units, you are only referring to gay men in reference to all women, whether gay or straight. Women, of any sexuality, are not allowed in combat units because all women are physically women.
Which is also a good point. If the main reason that women weren't allowed in combat units was the potential for unwanted relationships, then wouldn't it be okay for gay women to be in combat units? Afterall, the gay women wouldn't want to sleep with the straight guys, so then the only problems would come from straight guys who were willing to rape those women. And if there are guys who would be willing to rape fellow soldiers, then those are guys who shouldn't be in the military anyways.
Also, there are very few females that care if they have to share living spaces with women who aren't of the same sexuality as themselves. I shared berthing spaces with at least 3 women who were openly gay and a couple more who were bi, no one in my berthing cared. In fact, when we all were accused of being gay, we considered it hilarious and joked around about it. I'd be willing to bet that most of the complaints about sharing spaces are coming from straight men, not straight women nor gay men or women.
