Here's my take: If men and women working together having relations is a "problem," then you need to re-think the entire situation.
No private organization that I've worked for prior to the Navy has viewed this as a "problem." The fact that the Navy does is the "problem," and the only way to rectify it for good is to separate men and women entirely. And if it sexual relations really is a problem for fighting units re: morale, effectiveness, discipline, etc. (I'm not qualified to say so either way), then the only realistic solution that will work will be to keep them separate.
Because ending the career of two shit-hot PO2 due to having a relationship with someone he/she spends most of his/her time with is not a "solution."
But what do I know, I just need to finish this cup o' kool-aid.
