Help /lounge, I love my sister

Over the past year I've been trying to lie to myself, to think on something else, even got laid and tried to fall in love with other girls, anything but admitting what I, deep down inside, already knew.

I love my sister. Not in the way most brothers love their sisters, but in the way a man loves a woman. Not because of some silly fetish either; when I say love, I mean real, "I'll go to the end of the world for you" love.

My sister is only one year younger than me, making her 20, and currently doesn't have a boyfriend. She's pretty, at least to my eyes, but this is not fueling this. It's her personality. I like no other girl this much. We always had a lot of chemistry,  it's as if we were engineered to be together. Only we happened to share our parents. I'm sure if we had been born in different families, we would be the happiest couple in the world right now.

Lately, I realized I could not give up on this, but I'm kind of scared. I know this is fucked up. But I don't know what to do. I've been avoiding her for a couple of weeks, and this is causing her suffering, which in turn breaks my heart. I don't know if I should confess my love and face the consequences of experiencing a kind of love that's considered unacceptable in our society, even from her, or just let it pass and die inside.

Help me /lounge, what should I do? I think she may be feeling something similar for me becuase we are very close and she considers me attractive, but I don't know to what extent this may only be wishful thinking on my part. Knowing her, I'm sure she won't be angry at me if I tell her how I feel, but I don't know for sure if she'll feel the same about me. I'm positive our parents and everybody else in our family and community will oppose such love, but if she loves me, I'm willing to face all of them or move to some other country to start a new life with her. But I wouldn't want to put pressure on her or make her feel uneasy, so while I think I should confess, I'm not 100% sure and I don't know to what extent what I think is distorted by my strong affection for her.

So here's the update. Like I said in my previous post, I've been very busy these days, to the point of not even going online at least to check my Gmail for several days in a row, the main reason being my sweetheart. We've been going out almost every day.

We have so much in common and can talk about so many things we never get bored of it. When I went out (informally) with other girls in the past, I usually ran out of subjects to talk about, and I usually had some uncomfortable silence. But with my sister it's the opposite: we start talking about just anything at the second we're out of home, and stop talking before opening the door hours after. Believe it or not, part of it is thanks to the intarweb. I know so many stupid facts and have snippets of information on about any subject from random /b, Wikipedia and Googling, and she loves it; sometimes I think she picks strange subjects just to see if I know anything about them. Still, we are so uh... familiar with each other ( ;) ) we could go silent for several minutes when being together and it would not feel uncomfortable.

My mother did notice that we're going out together a lot lately, and asked if we have some friend in common. Since we don't want to have to explain this to our parents, at least for now, we just said we do a lot of shopping, go to videogame stores, etc. However, since then we've been a bit more cautious with it. Now we go out separately and meet somewhere in a few minutes.

I can tell that once you get over the initial doubts and strange feelings of dating your sister, you get used to it and see her as a regular girlfriend, only with the added bonus of the incest fetish you may have. (I did have a bit of an incest fetish, but heck, I never thought of making it true! And like I said, I love my sister as a woman, not because she's my sister and not because of some incest doujins; I'd love her just the same if she weren't my sister at all.)

And now the information you're probably waiting for: we've finally been talking about sex and having sex together (we used to talk about sex before this, but since we started dating we kinda avoided the subject, or rather did not dive deep into it). She said she thinks it's only normal that we have sex if we're going out, and that she's ready for it as a woman, but not yet as a sister, so she asked me to give her some more time, but she assured me that eventually she'd be willing to, and that she's serious about our relationship and hopes it turns out well. That last bit gave me a very warm feeling and I couldn't help but hug and kiss her right there when she said that. I told her I'll wait all she needs to feel sure and comfortable of what we do. After a few seconds of cuddling, she said I'm officially authorized to fantasize about her. After that day, we've been making more perverted comments every now and them, which are always received with a grin and occassionally a hand here or there. So we've been kissing, cuddling, and making some funny remarks.
