My sister was on facebook earlier and I remembered something she'd said two years ago at my brothers wedding; she was quite drunk, but whispered that she was bisexual. I remember whispering back that it was cool, and fine with me (obviously). Anyway, just five minutes ago I told her that I could see the beauty girls had to offer, but I also told her that I liked my coffee like I liked my women sexually: I don't like coffee. (Well I do lol, but that's not the point). With 14 siblings, I told her that I liked guys. Her response was that she has had a girlfriend for a while now and my older sister knows about it. I said that's really cool, and all I want was to find a cool guy who wants me. She didn't say anything else, but I hope this is the start of something beautiful.
Congratulations on coming out to your sister! Great that you have decided to come out to her. Having the support in/from the family is definitely helpful! Well done.
