I have nothing against people who like futa, yaoi, or yuri.
All I ask is that you keep it away from me. I like my 'original-flavor' sex, thank you very much.
(Monsters I can accept. Usually. But somehow, despite all the madness I've seen in hentai, science fiction, fantasy, and reality, my mind just goes "I draw the line at genitalia swapping genders.")
Normal sex is definitely the prefered, but futanari yuri isn't bad every now and then. Just no yaoi please. You can kept it all. I'm fine with you having it...
I generally like stuff that could be feasible anatomically. So, strap-ons/dildos on girls to fuck whoever? Hell yeah. Actual dicks? Let's keep 'em on the guys, please. No dicks involved, synthetic or otherwise? Well, okay, but I'd rather read about two dicks involved rather than none.
