Entertained for a little while going to this... I don't really think I want to call it an orgy, but it was an orgy.
The weirdest thing was the entertaining part. I'm really weird with sex given that I haven't had that many partners and I'm deathly afraid of STDs. I know way too many people who contracted something.
My answer of why I entertained it was simple: The girl that asked turned me on so much that reaching two decades after, thinking about her still starts revving me up.
Interesting side note: I was right. Love was spread that night (and into the morning), and also communal herpes.
College in another country, yo.
