You can click the close icon on ads and say they aren't relevant. It might start to make them disappear. But it's up to advertisers to choose the demographic they apply their ads to. In all honesty I don't think you can segregate by marital status when you create an ad, so they're probably just targeting men within your age range.
Is your profile not linked to your wife's as her spouse?

This seems to be the explanation. I went on and filled in some job history (security guard) and sure enough, the dating and "hot girl" ads disappeared - replaced by ads for security vests and training videos.
Blank profile = advertisers who'll advertise to anyone.
I get the same horrible ads on facebook. I intensely dislike being shown ads targetted at dating, with pictures of women designed to be sexually enticing.
I dislike it enough that I would never use facebook outside my business interests - and even then only on as limited as I can make it.
And what are the chances I'm going to let my kids on facebook, give advertisers permission to market stuff like this to my kids? Probability of that happening is 0. They'll get facebook when they leave the house - after which point they probably won't care anyway.
Perhaps I'm a prude. But if so, I'm not alone. Though I guess I'm alone enough that facebook doesn't give a rip :).
