Axident, to your statement, God / Jesus constantly asks no requires us to be what we are not. So even if there was a homosexual gene (which I personally don’t believe) God would want us to fight against it just like any other disease or disorder.
Paul says we need to die unto ourselves and hate what we are and beg God for there to be more of him and less of us in us.
So yes, God wants us to be something different then we were born as. Remember we are not born the way God originally created us to be…we are born corrupted and with sin so of course he wants us to be different.
