I used to think peeking at the pisser was my vice and not in actuality the enjoyment of many hundreds of others, straight and gay! Let's be honest, as long as you're only looking, and only at adult men, then there is no real harm done. Most men practice an unspoken agreement that eyes stay off of each others cocks at the passers and in the locker rooms, etc. But its only a social agreement not a promise. And not everyone has signed that contract. I'm not sure there's any harm in the videotaping of these episodes although one might argue emotional damage, etc.. Ive not read anything on the specific topic so can't comment. And of course we all know it is illegal. I shouldn't have to point that out but i feel that i do.
Personally i find these films a real turn on. I'm a true voyeur at heat I guess.
