Eh, I went through a stage. I started with hentai a few years ago.. Yea, an early sprouter.. I see what you mean by with the whole People wont mistake it for real Life..thing. I know that girls dont like guys watching porn... and Hentai isnt porn... so its safe?
Somehow, I dont get that many urges off of hentai though anymore. But, you do whatever you think is right. Maybe you should try making a story in your head to jerk off too. Thats what i do when my computer connection dies.xD
