There's a difference between lusting after a 30 year old who could be your kid and an 18 year old who could be your kid.
I adore
Michael Cera. I think he's hot, and I know that if I were 15 right now I'd have pictures of him on my walls, be thinking of him at certain discreet moments, etc. But 30 year old me to say "I'd totally fvck him", "I want to see him naked", "Wish I could hit that".....that's just creepy and gross.
IMHO....there's a point where young is too young, and it ceases to be funny or sexy.
And yes, I practice what I preach
