personally I think Demandred is a gay man ... he only like Ilyena because LTT wanted her 
Yeah, DomA and I once discussed this. Some of the top Nazi generals were gay and it's likely that Demandred might have been gay himself. The fact that LTT didn't want him turned his yearning into scorn.
Anyway, back to the main point... I was only joking obviously. However, Moridin should be careful what he commands Moghedien to do esp. to obey Demandred in all things. Asmodean used darkfriends under his command for sex.
I've considered it a few times and it would not be shocking ... especially from his POV during the Cleansing.
Asmodean was a saint compared to Graendal and Rhavin
With two bisexual Forsaken and one into S&M, it's likely the rest are straight - instinctively of course. It's also likely they're so paranoid and tainted that none of them could hope to hold a normal relationship for any small amount of time. Rahvin was pretty much the best looking guy on the planet and he still had to flatten women's minds with Compulsion to get them into bed.
