You know what...
thats a great article, its logical and it plays into the fact if your genuinely nice he'll do what you want.
I think that advice could be used for both men & women resolving any problem.
Not just this one.
Mind I say this but I constantly look at Womans butts even though I'm perfectly happy with the one I've got, a good eye-full is like a sumptuous feast of that food you love and are like "I just need a little bit more" even after your 5th/6th helping, except this isn't for your taste buds, its for your eyes, it makes them feel great!
The problem is even though my girlfriend is more attractive than 19/20 girls I see walking around on the street, she is next to me holding my hand and therefore her bum is not in my line of sight, and therefore not an option.
I'm completely honest about where I'm looking and will "follow" things I like. I even comment to my gf if its worth it. You could say she even benefits because I'm giving honest opinion on what I like and she can try to be like that for me.
I may just be a egotistic, sex addicted, emotionally unhealthy man/perv saying this...
But if you do everything in that article and he's still looking at other women, you don't have anything to worry about.
