You have to understand that there are plenty of other factors that contribute to the whole. What you are seeing now is simple mannerisms. With a child that young it is understandable that he is copying the elders that he sees the most, and if he doesn't have a male role model around, then he can't invent those mannerisms. The dynamics of psychology that leads to an eventual choice of homosexuality includes much, much more than just hormones. They may play a small part, really secondary, as in making him smaller, gentler, and therefore more prone to the kind of possible alienation that can suggest homosexuality to him, if he's been led to believe it is biological. My roommate in seminary was extremely feminine. One of his constant frustration was that people kept thinking he was a woman on the phone. But he dated frequently, much more than I did, and was definitey heterosexual, and had no problems relating to women as a man should. As your son gets older his medicine may be able to be balanced better and either extreme can be avoided. He will eventually begin modelling behavior that he sees from men rather than just females. As long as those basic needs of affection from both a mother and a father are met, he'll grow up as a well adjusted person, hormones or not, and live a very happy life. Just remember that every child needs emotional nutrition as well as physical nutrition. Make sure he gets a proper, balanced diet in both.
