Ah anime. As if regular porn wasn’t bad enough, now anime porn is all the rage. Trouble is, a lot of anime comes awfully close to being porn-ish, and anime itself has inherit problems that make it a sticky subject to being with.
Anime characters typically have poor distinction between male and female. Men are often drawn without facial hair, and lack real masculinity. Women are often drawn as very young girls, but are intended to have a high level of sex appeal and “cuteness”.
I don’t really have a problem with good, mature anime, but in general, I think it can be a dangerous thing that can distort someone’s idea of what is attractive, masculine or feminine.
