Its wrong to call him a pervert, he's done no-one any harm but himself and perhaps he can't get himself a woman? more pidgeon holing & stereotyping going on methinks
Hmmm. But is it trying to have sex with an inanimate object or masturation (akin to a woman using a vibrator) or person substitution?
or all 3 - whatever the motives, I think it would be awful if you were reduced to it. and yeah 24mm is small - might exsplain why he avoided having sex with real people - because someone he showed it to laughed.
Some of the replys have been amusing though
