I'm 45 and still in love with the succubus. ;)
I hope no one actually beats off to mediocre drawings of fantasy creatures.
I can no longer speak for what 12 year olds do today, but the access to porn back in the day at 12 was... non existent ;)
I never really wanted a tattoo, but if I were to get one it would have been that little succubus from the MM.
I never found them erotic, but I did find some of them embarrassing to show to other family members who might have been interested in what my D&D hobby was like. Yes, the Succubus is the one that mostly springs to mind, but there is also the Erinyes,while the Marilith, Harpy and the Lamia were all too monstrous to be sexy but still had big bare breasts. And for extra weirdness, do you remember the female weretiger?
Sheesh, even in the late 70s porn was easier to get than a sunburn. Those old MM nudies were LAME.
The pic was hot, but it wasn't enough to make me want to crank one out.
I liked Isis in the D&DG. Just sayin'.
