I need your ideas….to help me out of a dilemma

I am about to produce a book of poetry with images. Having had a few discussions I am confused about what sort of images to use. Some of the poetry has sexual imagery and so, should I go down the route of romantic, mildly erotic or erotica images or go for visual imagery that gives hints and is beautiful.

So what would you vote for.

What type of images might make you look or not look at a book.

Please help me with this by giving me your views.

or something more explicit?
