“If you want my body AND you think I’m sexy, come on baby let me know,” sings Rod Stewart. He puts a lot of emphasis on that conjunction, which I take to mean that both conditions must hold before the imperative consequence obtains. Thus, if you think he’s sexy but you don’t want his body (perhaps he is only astrally sexy), you don’t have to let him know. Likewise, if you want his body but you don’t think he’s sexy (perhaps you want his body for science, or meat) he doesn’t want to hear about it.
