I started pretty young; been about 9 years now. I started a little earlier than that off of hentai flash games, but ended up going into hentai manga shortly afterwards.
A lot of people started pretty young it seems. Started at 15-16 with pictures, but than the desire grew and shifted to vids. Now both are being enjoyed!
17 or 18 i guess? At some point just watching porn got boring, start to read hentai because it offers some interesting stories with action, and doesnt take long for me to move to watching
a couple weeks, no so much time. I go out and back off this stuff, so adding the time, it would be not so much. But the fist time was 4 years ago... i got back for the third time hue
