The YouTube video description gives a good summary of this talk by Melinda Selmys:
Melinda Selmys gives her talk at the 2012 Courage Conference titled, The Straight Story where she gives an account of her life where lived the lesbian life style and then came to God and became wife and mother of six children. She then gives her assessment of the origins and ramifications of her same sex attraction, discussing whether it is intrinsic to a person's nature as many would have us believe today or whether it is simply a temptation for some people which can be resisted like any other temptation as part of one's overall effort to conform their will to the will of God. She includes many references to philosophy, theology, psychology and to her own personal experience to form an intelligent, Christian, broadminded view of a very complex issue.
What I found most interesting about this talk is that Mrs. Selmys demonstrates that homosexuality is a complex issue which does not always perfectly fit any pre-defined narrative. In doing so, she goes beyond both the standard secular take on homosexuality and the standard Catholic take on homosexuality (but while still remaining faithful to what the Catholic Church teaches).
