Sup dude! How ya doin'! Been enjoyin' hentai for a few years myself :D
The very first being the 2010 manga "Yuria 100" (its about a living sex doll that doesn't want to be a sex doll XD)
When I saw what was "down there" for the first time, I was on the lookout for more lol (granted it was censored, but the fact that they even showed "that", was enough to arouse the ignorant (and innocent :I)) me.
What about you? What was your first ero-manga?
Any favorite artists?
If I had to pick my no.1: It would be Inoue Kiyoshirou
Discovering his work at the same time I was discovering hentai is something I consider a blessing, and a curse; as he set the standard for all other hentai (of which only a few have met).
Anyway, hope we can have a good ol' chat ;)
