How much gay content is in this game? I get that it can be skipped but random dudes constantly flirting with the MC is not appealing for me at all.
There are 3 regulars that you deal with, they are in your base so you will see them and interact with them on a regular basis.
Most prominent is Andras, the big red demon that is one of you captors, there are a few scenes in which he will order you to service him. It really just a power play to assert dominance over you, you can pretty much tell him to fuck off every time. He is actually more into your wife anyways, but she can also tell him to fuck off every time if you want.
The next is Draith, the submissive twink dark elf, he is clearly into you (or any strong male figure really) and lets you know he is available if you are interested, but he doesn't really take a pass at you directly. Draith will respect your boundaries, but he also wants you to know he's still available if you change your mind.
The final one is Skordred, the dark dwarf. He will make one advance on you and if you shoot him down he will never bring it up again. Its not hard to even avoid that one advance completely.
There are other characters but they are mostly one off characters that you as the MC have to initiate relations if you want them.
Edited Addendum:
There is also Greyhide, the minotaur blacksmith, he is a regular in the castle but he doesn't persue you. You can however initiate a drunk make out session with him that will lead to more. I suppose Greyhide is actually bi though because he can also hook up with your wife instead of or in addition to the MC, possibly leading to MMF threesomes.
