Yeah. We've been friends for a long time, too, so there was that also.
My problem is that I'm not easily attracted to people who I just met, so I take a long time to get to know them, and then somehow I'll suddenly realize that over time I've developed an interest with the person as I've known them as a friend. But obviously by then I'm not on the radar as someone to date.
That and I'm not exactly a natural when it comes to flirting or displaying sexual interest. When that comes into play I stiffen up and can't shake the idea that it would make me look like an ass. It's even more like that in my case since these people are people I've been friends with for a long time, usually, so the change would be weird.
Even though I know that's not quite true since I see it work for other people, but that's the way it is.
