Pardon, but I´ve to get some things STRAIGHT!
In the first place, the permission to have sexual intercourse within military bases is for heterosexual couples. Although homosexuality is not illegal in the armed forces, it means to get placed to a task where you have not much contact to others. There will be no gay Sergeant training recruits! I don´t know any gay soldiers, but I´m sure there are a few. Those are as silent as the gays in the US military are, and this is better for them and for us.
