Anonymous Encounters

There is an entire culture of humans who derives most of their sexual pleasure from "hooking up" with people just for sex, with no other real connection.

Thoughts

For some, it's about instant gratification.  Taking the time to get to know someone can be time consuming.
For others, it's about insecurity.  They feel like if someone gets to know them, they won't be interested. So rather than risk rejection for something that matters, like a relationship, they play a game to get sex.
For some it's about feeding a need or addiction for sex.
And for some anonymous sex is a way to start a relationship.  For some in various Fetish Communities, it is easier to find someone who shares your physical needs and then build a relationship from there.

If you have had such an experience,  and you are comfortable doing so, please share.
