If it is part of your biology, it is God given. Epigenetics is a biological process. The Devil does not tempt children in the womb, since they have no language with which to be tempted. What tortures people is not their natural urges but that ignorant teachers and family members (and Popes) condemn them for what they find natural. Those teachers and family members and clergy have much to atone for. Enjoy purgatory, if you are lucky.
