While i don't underestimate men's desire to fuck everyrhing, i never understood why sonic characters are SO sexualised by it's community.
I see them more as pets than something i would want to stick my dick in, i am not a furry so i can't mention another series, but i'm sure there are games or movies more sexually charged that the kid's product sonic is.
Having said that, i do remember when i was a kid being a little ashamed when playing sa2 in front of my father when he saw rouge's bouncy breasts, because i noticed he had the neuron activation.
