Two of my very very best friends in the whole entire world are boys. One (friends since 6th grade) is a confirmed bachelor, so there's no sexual tension there.

The other, I've never felt any attraction to (I can't say the same in reverse, obviously). If I did, or he did, I wouldn't end the friendship.
For me, the only question now is finding suitable women for our wedding party. There will be so many boys!
