Unhappyguy said it pretty well.

Granted, we don't personally know you, and none of us are going to trace your username or something James Bond-esque like that, so it might feel different from discussing it with people you know in person, but you did indeed tell us. And no one here thought you were weird or gross, now did they?
I'd wager very safely that your friends all probably have a story they could relate about something along these lines they did when they discovered themselves. Neither you nor they are hiding something by not relating that story. Like I said, it's personal.

You shouldn't feel obligated for that to be known.
So like I said Jacko, please try to let this go.

You're a perfectly normal young woman with nothing to be ashamed of.
