Glory Hole

If you are looking for proof that men are capable of completely anonymous, objectified sex, look no further than the 'glory hole'.  This is an ironic name for a place, often a public restroom or adult bookstore stall, where there is a hole in the partition between stalls.  A man puts his penis through, and oral sex is provided anonymously by the man on the other side.  Technically a woman could  be providing this 'service', but let's be realistic.
