To each their own, but both as a voyeur/exhibitionist and as a photographer/model, these two things get on my nerves.
1. Men who don't let their wives/girlfriends dress sexy or pose seductively, because they're jealous of other men looking at her.
You fuck with your cock, not with your eyes, jeez!
I could also go into fathers who police their daughters' wardrobes because they don't want them to dress like "sluts", while turning around and high-fiving their buddies when a group of skimpily-dressed "sluts" passes them on their way to the bar. If you enjoy women's sex appeal, how about treating the ones who show it off with a little respect? Sheesh.
2. Women who say they won't pose nude because they're saving their body for their significant other.
Even if the entire world sees you naked (which is not a big deal, by the way), your husband/boyfriend is still the only person who gets to have sex with you. And that's a pretty big fucking deal, in my opinion.
Like I said, everyone can make their own decisions in life, but these are two things I don't personally agree with.
