Here is an opinion piece in the Stars & Stripes where a former West Point graduate advocates for allowing military personnel to have sex in the barracks and while deployed. Here is how she wraps it up:
What would I do if I were in charge? I’d abolish General Order No. 1. Keep the rules that protect soldiers from sexual harassment. But allow deployed officers and troops to have sex while at war. West Point should come to its senses as well.
West Pointers and other military servicemembers endure tremendous sacrifices. We appreciate the adoration and respect we receive. In that same spirit, I ask the public to accept and forgive our weaknesses. It’s OK to be disappointed, but please don’t be misled. Beneath the heavy combat gear and impressive uniform, we’re human, just like you. [Stars & Stripes]
You can read the rest at the link, but the biggest reason there is no sex allowed in the barracks is because of the threat of increased sexual assaults.
