There is incredible variation among boys, girls and everything in between. Some people are even easy to characterize at reproductive pluming level. And that is certainly not all there is to gender, gender expression or sexuality. There is not hard correspondence to reality that you imply. And these things are NOT a mental disorder.
God made me trans. I was born that way. Should I deny how God made me? You can't excuse this limited view of yours as being what God intended. That just hoists your own prejudice up to the God level.
