Ok, it is dark. You can't see anything and nobody else can either. There's no such thing as an STD or getting pregnant (Nothing bad can happen period) Someone comes and sits beside you. They smell great and they say, "Here I am, I'm all yours"! You reach over and find they are the sex you are most uncomfortable around. In other words, maybe someone of your same sex? Maybe someone with a huge penis and you're afraid? Maybe her vagina is just as wet as yours is getting quickly? But still, nobody would know, and you have 48 hours to do any and everything with that person you could imagine. then, they are going to go away. You'll never be around them again. They don't know you and you don't know them Would you spend those 48 hours making love to them in ways you might otherwise be afraid to try?
