If watching porn with a male partner, I would prefer to see M/F in any combination. So there could be any number of males with the females and vice versa. What I don't like is the fake F/F action that passes for F/F today; it looks so fake! (If it looked like actual lesbian sex, I'd certainly enjoy it more.) Same for M/F/M where the men don't act comfortable with the other guy's body. I don't enjoy most multiples porn out there that I've seen so far, except what I've seen on (and I really like in general) the "couples friendly" porn like on this site
. It's plenty graphic and all, but it's so much better done than the crap that is mainstream today. Most importantly for me, they should appear to be into each other and have real orgasms!
So queer friendly porn like the Crashpad series is also what I'd watch with a partner. I find most of the queer-centric porn to be more about really turned on people having mutually satisfying sex! Real people having real orgasms is what cranks my motor and what I watch privately is no different than what I'd watch with a partner (providing they didn't find something less than titillating in what I like, then I'd not watch that with him).
