A couple years ago, I had a (bisexual) guy friend who told me that Billie helped him determine his sexuality; Billie was one of the first men he was ever attracted to.
On the opposite end of the spectrum, I have a girl friend who tells me that Billie confirms that she is "definitely not attracted to guys". Honestly though, I can't help but feel that Billie would appeal to people of all sexual orientations because while he doesn't totally lack masculinity, he still has that petite "girlish figure" that we all love so much. He has a somewhat androgynous look, and I say that with nothing but love and affection. I wouldn't want him any other way.
