A weird situation

I am 26 years old and Im in a strange situation. You see Im married to my wife and I have a daughter but I think I might be gay. I love my wife and I find her attractive but not as much as I find some men. In fact other than my wife I find no women appealing. Its hard to explain properly but I feel like things are changing and Im really confused. Anyone out there have any idea whats up with me?
