I am a married mature man but everytime I watch the first guy I get a rock hard erection and jerk myself off while I watch him cum and then I do too so hard.
I'm a 73 year old straight guy - I've often said that jerking off is a manly thing to do - a celebration of the best part of being male. It really does unite us in a way - I'd love to get the chance to masturbate with a bud or two.
