Is it weird that I can understand things like tentacle/monster hentai but find loli/guro incredibley gross? Most standard hentai is hilarious, I agree
Hentai... is undoubtabley weird. The Japanese are in general very weird in the sex department.

Check out the burusera shops. I've had numerous confirmations that they exist but damn... I don't think I'll ever truly believe until I see it for myself
but yeah, back to hentai. If it comes to fulfilling odd fetishes that are impossible in real porn, like the tentacles or whatnot, I don't find it particularly sick. Maybe a little weird, but not sick. Whereas, things like loli/guro makes me uncomfortable. I know it's not real, but enjoying the concept of it is kinda sick. That sounded like a contradiction... oh well.
One think I find strangely hilarious about hentai are dickgirls. I don't even know WHY I find it so funny, but the ways in which these girls magically aquire dicks are just so unreal. Two most common I see are: overgrown dick-clit, and the other is where dick literally springs out from out of the girl's vag.
