On the other hand, he loves "boy things" the same, if not more. He plays with RC cars, makes paper airplanes, has miles of train tracks, is addicted to video games, and is just as much a boy as any other kid.
I've been criticized before for allowing him to do the same things as his sisters, but I don't see the reason why. There is no need at all for me to tell my little boy that he can't play dress up with his sisters. Grown men dress in drag for dares, charity events, and a zillion other reasons. This is just a little boy playing with his siblings, innocently. Rock stars paint their nails, men carry "messenger bags", etc.
If he, in the end, grows up, and decides that he is attracted to other men, I'll love him just the same. I won't go around blaming myself, either. Not for allowing him the freedom to be himself, his world, and to bond with his siblings without restraint. I don't apologize for my decision to let him be who he wants to, while guiding and watching carefully. I do, however, defend my son, who is still innocent enough to only see that his fingers looks colorful and sparkly when painted, not that he is violating the other people's perceived notions of gender roles.
