The x in sex

By David Bainbridge. His earlier attempt to popularize science, Making Babies: The Science of Pregnancy published in by Harvard University Press , was stimulated by the birth of his son. He has sufficient knowledge, as well as the extraordinary ability to communicate it in a breezy, highly readable fashion that is both entertaining and informative. The present book demands little effort to comprehend and deals with important subjects not usually discussed in the popular press—that is, the genetic basis of sex differences and X inactivation.

Let's put the X in sex.

I got a letter just the other day She sent a picture, but she didn't sign her name She wore high heels and a little black lace I knew her body, but I couldn't see her face. She didn't leave a number, not an address or a clue But something in that photograph reminded me of you. Baby, let's put the X in sex Love's like a muscle and you make me wanna flex Baby, let's put the X in sex Keep it undercover, baby let me be your private eye. I got a call in the middle of the night Heavy breathin' never sounded quite so nice She said "Ooh yeah, I wish that I was there" I asked who was calling, but she wasn't playing fair.

The song was written by Paul Stanley and his frequent collaborator Desmond Child. According to The Official Price Guide to Kiss Collectibles by Ingo Floren, the two songs let some fans wonder about the new musical direction of the band" because they "were produced with lots of keyboards over a dance-orientated beat". The promotional 12" vinyl version had several remixes that were intended to be radio-friendly. Brett Weiss' Encyclopedia of KISS describes the song as "a typically fine, typically flamboyant performance by Paul Stanley", which "begins the record [the album] on a party-heavy note".
