I saw this, and just
had to answer it. The answer would obviously be
yes. I think everyone has, to be honest. Initially, I tried to keep it secret, and it wasn't altogether hard because it wasn't all that "large" a crush at first, we were just good friends. (My closest "best" friend is
not my husband, although I consider him one of my best friends, if that makes sense. My best friend I've known and been close to for almost fifteen years. I've only known my husband for about five. No comparison, really). And to be honest, it wasn't hard to keep it secret, because like every other teenage boy on the planet, he was clueless.
He eventually found out, we tried to be friends with benefits, although moving across states put a chink in that, and we're still good friends to this day. We're both in serious relationships with someone we care deeply for, and our significant others even get along *grin*. So, I suppose, if it blossomed into "anything more" it would be a deeper friendship.
