Hi!
That's quite an amusing post. Funny. I have a friend who told his father he liked to play with guns. Yun pala he meant he wanted to be one of Charlie's Angels.
As a psychologist, there are different viewpoints to how one becomes homosexual. It's more like a nature versus nurture argument. Environment or genetics...there are several valid takes on BOTH ends, but in my opinion, it may be biological. It doesn't mean that there is a "gay gene" or something inherited from you or your husband. A person could act gay if he was exposed to peers and gay adults as a child, but in the end, turn out as straight as Arnold Schwarzenegger. Then again, we hear of boys and girls raised in "regular" environments, and they suddenly come out of the closet after college.
The main question is...What's wrong with being gay? 
I'm a straight married man with a young toddler. My son is a solid boy, accepted a Jujitsu intro classes at 2.8, but SERIOUSLY if he turns out to be tutti frutti, there's nothing I can do but love him the way he is, and encourage the positive.
I once was asked by a fellow martial arts practitioner "Pare, ano mas gusto mo...lumaki anak mo barumbado at nambububog, o maging successful na executive tulad ni M.P. (not Pacquiao hah) pero bakla?"
Uh, pretty shallow but it gives you a little foresight.
If your son is going through a phase, which is most likely, just let it go, and don't repress it. If it turns out it's not a phase, LOVE HIM, TAKE CARE OF HIM. Guide him. Mahirap sa magulang na magging iba yung anak nila, pero mas mahirap sa isang bata struggling with a secret, struggling to be different and yet be mainstream. It's not your fault, it's not his fault. It's not even a problem.
If it's about wanting an apo, sorry to be frank, but that's what you want. What about your child should he grow up even straight, and not want children at all? On the flip side, actor Neil Patrick Harris and his partner have lovely twins.
If you nourish his mind and his manners, no matter what he grows up to be, he'll grow up a DECENT HUMAN BEING. And I think that supersedes the idea of being gay or straight altogether.
