I am a (heterosexual) woman and the only porn I really like is D/s stuff. Threesomes if MFM or MMf (2 dom bi guys, one subby lady) But video is least favorite media. Written stories > pictures > video.
In real life nothing is actually hotter than one on one, it's the gold standard. Plain ol sex is great. Everything else is good but mostly because it makes that plain sex afterwards so hot. But power dynamics works best for fantasy, always has and I guess always will.
The girl/girl stuff id imagine it's because we believe the women are actually getting off, and it's easier to buy in. I don't enjoy it though, so can't say for sure.
