It's a common misconception that boys who like to dress up in girls' clothes, play with dolls and do other things which are stereotypical 'female' activities are necessarily gay. Not so! I was just starting to write a kids' story about this very issue, and someone's saved me the trouble... one of my friends just shared this link on Facebook:

Seeing I don't need to write that story, I'll spend the time sharing a few anecdotes to get your thoughts going about what little boys actually get out of playing with girls' toys.
