I experimented and it was a REALLLY bad choice! Help?

So, as curious horny teenagers do, I experimented. That isn't even the part that bugs me. It's that the person who was my... experiment partner... was my step sister. We're not related by blood... and I don't really see her as a sister figure, but I still feel disgusting. Now I'm swimming in the thoughts of how many people could hate me right now. A) we're both girls, B) it was borderline incest... kinda... and C) I EVEN DID IT AT ALL!!! I thought maybe I could get over it, but it's really hard when you live with the person half of your life. I don't even harbor any sexual/ romantic feelings for her, so part of me is sad I did it with her and not someone I actually like. We didn't go all the way... but still, it's the closest I have ever been. I need advice on either how to forget about it, get over it, or confront it. Grrrr... please help me

i know it seems hard right now, but u will get over it. make sure she knows u have no intentions of doing it again tho

Call Jerry Springer!!!

You're neither the first person to experiment nor the first to do something foolish. You'll get over it.
