Is sexual desire irrational?

 Following the philosopher Immanuel Kant, Longino assumes that sex is morally problematic because it is difficult, if not impossible, to have sex without treating another person as a “mere means” to our own satisfaction. 

Sexual desire is irrational and leads us to reduce others to their sexual body parts, and thus is objectifying, dehumanizing, and degrading. 

Longino adds a feminist element to Kant by arguing that, because men have greater social power than women, men are able to use women as instruments to satisfy their sexual ends. 

Pornographic depictions of heterosexual sex, then, glorify and promote the immoral and subordinating treatment of women by men.
