This was just way to odd for me to pass this one by...LOL
Just because your friend wanted to be a woman doesn't mean that he wasn't into women before the change or after she became one. The human mind works in strange ways but, to each his or her own. It's not my place to judge... People are people.
I think she may have been feeling you out but, also you are friends, and she didn't think much past here's my page.
I have plenty of friend that are gay, and just because they are gay doesn't mean I have to freak out that they want a piece of me. Even if they did, they know I'm straight, and not to go there. Out of respect, and friendship.
Also, your friend was your friend before you found this out. Is it really that important to you? Besides, look at it this way; your friend is transgender. That in itself, most people would have been freaked out by. You've accepted her that far, why would this be any worse. But that's just me.
You seem like a nice, intellegent girl and I guess 'sexy as hell and lovable to DEATH ' modest (LOL), Canadian ('egh) (BTW... I had a Canadian GF and she was as sexy hell and lovable to DEATH... GRRRR!!!) so I guess we have to believe you on that one.
Seriously, if it freaks you out maybe you really just need to sit down with her and talk about it and sort of set the ground rules. If she is your friend she will understand, and respect that and you. Just my 2 cents. Much respect for all.
