Parenting Advice?

I was raised Catholic and have been debating for awhile on whether to introduce my young son to the Church. He's too young to have any indication of his sexual orientation, but I want to make sure he knows that the Church's stance on LGBT is wrong and that no loving relationship is condemned by God.

Anything I can do/not do to make sure he never feels sinful for who he is, if he is gay/LGBT?
