I do notice things - girls! I love looking at hot young female high school asses, and if i'm really lucky FEET! Yeah, bring on the summer, sandal weather! If i see a hot ass, or some gorgeous little teenage feet then yes, i get abit distracted - but i go to the gym to train.
I would never dream of going up to a schoolboy and owning him in the gym. Just think about it for a moment. Its wrong. Yes it makes an amusing tale on getbig, but come on man, you're 34!
