Hentai. Because perfection can be drawn and edited to suit the needs of the artist. Real pornstars age every second. What I don't approve of is Hentai voice acting.
It has been my observation that hentai lovers are the evolution of anime watchers. Captain Obvious strikes AGAIN!
Hentai is hilarious. Look jiggly boobs! Look, giant sticks! Look, buckets! It's like a tragedy of humor, only funnier.
Real thing, but its even better to have a gf who loves to watch hentai. Its real fun to act out hentai.
I prefer hentai because I've had sex - which makes a bit icky when watching real porn now coz I end up thinking of my bf as the guy :s plus I do like tentacles and weird shit in hentai :3
