Yes. We are still good friends thought we live on opposite sides of the continent. When we were in high school, he told me he wished I could have been a girl so that i could be his girlfriend, he liked me that much.
Yes. I had two best buddies all through school. We hung out from third grade (1973-74) through graduation (1983). The three of us have remained close through the years and visit often. One is bi, the other straight, so the three of us run the gamut.
Yes, my best friend from seventh grade onwards (a straight guy) is still my best friend today, and we now live in the same city (not where we grew up).
