This is fake, obviously.
Research shows that the average blockhead rather has girl problems as in, they can't date or they can't find the right one.
And this might indeed be one big dare as someone already said.
Once, a girl (not bad looking, but slutty) tried to get me to have love with her.
But luckily i don't really feel something for a one-night stand or anything and i was friends with a friend of her, who was pretty angry with her.
And she told me that it was all a contest with another girl to take the virginity of as many boys as possible.
Thinking about it, makes it seem weird, but i could totally see that being the truth.
I am not that good looking, never had a girlfriend so far and always been a bit of an outsider (together with others <3).
But i never regret that decision.
I talked to her, she complimented me sometimes with my ass after that and stuff like that.
I believe we even talked about the contest, but i am not sure.
It's been quite a while now.
TL;DR
It's a trap.
Ignore 'em.
