IIN that I touch my sister sexually? (not what you think, probably)

I'm sorry to inform you, but two females cannot reproduce. :/

OP, I'm pretty sure it's not normal. However, as long as it doesn't get out of hand I'm sure it'll be fine. Your sister is growing up and she'll go through some phases where... well... she'll probably have phases where she'll be so horny she can't stand it. And that's normal.

You on the other hand, as you are well aware, have some issues. How you wear your hair and dress is not a sign of your "social status", it's your personal preference. When you say you're afraid to befriend people, this tells me that you've probably had painful previous experiences with others, and this is also normal. You can't hide inside forever. The world is not as painful of a place as it may seem, and depression is easier to break out of then you may think, even without pills. But you'll never know what you can accomplish if you don't try. Use the wealth of the internet to your advantage.

Good luck. ^_^
