Gay or straight, sexual relationships are bad for unit cohesion and discipline.

In some rear area support units it is a severe headache for the leadership, but it is manageable.

In a combat unit, however, it can be deadly. Everyone has to rely on everyone else. Perception is as important as what is actually going on. If you introduce lovers into the mix you have to worry about whether they are doing their job or doing each other. This doesn’t effect just the leaders either, everyone has something to say about it. And then think of having to depend on an ex-lover to watch your back.

There are always interpersonal difficulties that have to be handled and overcome but adding love and sex into the mix is very dangerous if you want a reliable combat unit.

It is more than just a matter of what is socially expectable.
