Totally ignore his feminine features and develop a good father-son relationship. Take him to ball games, sneak him some whiskey when his mom is not around, ask him to help me with yard work, give him advice about talking to girls.
In other words, be a good masculine role model for him and give him the attention he needs. At least give him a chance to develop into a normal man. If he doesn't, well, at least I might keep the degeneracy to a minimum.
