I'm a party pooper, but I don't check out other men. I do notice if a guy is good looking, but I don't think about it beyond the initial observation. I am a people watcher too, but I do pay attention to exactly what my thoughts are thinking. I never have daydreams about other guys or anything like that. it is a choice I make because it would be easy to pay more attention!
And, in the past eight years, I have seriously NEVER caught my husband checking out another girl. He doesn't stare at them when they walk by. I have never caught him looking at another girl. I mean, he's seen other girls, but his gaze never stops and follows. He'll stare at me, though...hehe. He still treats me like I'm the most attractive thing he's ever seen;-)
If a sleezy commercial comes on that's all sexual, he'll look away. At first I thought he was just doing it when I was around, but I would spy on him if I was in a different room (I just couldn't believe a guy would look away even if no one else was around!). I'd hear a commercial come on and know it was one of those sleezy ones, and I'd peek in to see if he looked away, and he would look away! It totally surprised me. And, I know he had no idea I was spying...hehe.
He never comments on whether other girls are pretty. I have to pry it out of him because sometimes I'm curious if a girl is pretty to guys that I don't think is pretty or I do think is pretty and guys don't, etc. He just doesn't like to pay attention to that. He feels like it's being disloyal to me to pay attention to other girls at all. He tells me I'm his dream girl and he only has eyes for me...ahhhh... I can't help but feel inclined to treat him the same way:-) I like it. I've never dated another guy who was like my hubby about this. But I really like it!
