In the perfect world it wouldn't and shouldn't matter. I have no opinion to offer on the ideology of whether women should or should not serve on a sub. You guys hammer that out. Lemme know what you come up with.
I will just speak of what I DO know, first hand, face-to-face, in da mix, experience of having served on several Naval stations amongst men and women sailors.
There is soooo much drama. So many games. There are so many "situations". Distractions up the wazoo. Can't be avoided, I suppose. (It sure beats having to spend the weekend with a buncha guys though.)
If I was to have to work in a 24/7, do or die, environment, such as a sub, as much as I would love the ladies, the distractions I have witnessed could, and most likely would, cost lives and material.
Chicks and dicks on a sub? NOT a good idea. Just sayin'.
