Sometimes during more intimate moments, things are known to just, you know, pop up...which is why this is so appropriate:

"A scandalously clever tour of the erotic arts, The Pop-up Book of
Sex provides a unique perspective on such positions as the classic
Missionary, the naughty Mile-High Club, the exotic Lotus, and the
whimsical Fantasy." Not your Mama's coffee table book...
