I like a smooth looping animation with text. The "gamier" representations of sex can be hit or miss for me. I'll take something polished and static over interactivity.

Becoming a Femboy has lots of Futa on Male, and Femdom stuff if you're interested in that sort of thing. The english is definitely broken, and the premise is absurd, but theres lots of lewd content to sift through and the 2D artwork is actually quite detailed and unique.
