God loves you too much to ignore your sexuality.

People want to do what they want, when they want to do it, and how they want to do it.  People don't like being told what they can and cannot do.  This isn't a mystery, its obvious, a commonality of us all.  Our feelings about sex and sexuality are no different.  In order to fulfill humanity's desire to be autonomous, to make our own rules, elements of society have always sought to ignore the clear consequences of sexual activity outside of marriage, whether it be heterosexual or homosexual, the desire to be autonomous and reject limitations remains the same.
Sexuality has significant consequences for individuals and society that we ignore at our peril.  It can be a force for good when contained within a loving marriage, an expression of fidelity and love, but it can also be a powerful destructive force when it exceeds that boundary, resulting in STD's, divorce, rape, abortions, and all manner of non-marital sexuality, including homosexual expressions.  Sexual expression has to have limits, no society can function without them.  Biology ought to be one obvious restraint on human autonomy, after all, it takes a man and a woman to reproduce, but even this fact of nature comes under assault when people seeking autonomy are willing to ignore nature and embrace homosexual and transgender perspectives.
God isn't interested in ruining fun, God doesn't want to quash happiness or love, but God, as our Heavenly Father and our Creator, is not going to sit by and let human beings pursue dead-end paths that are only self-destructive, he loves you too much.  God, in the created order, has set limits upon our expressions of sexuality.
All sexual expressions outside of the marriage of one man and one woman are sin, not because I say so, but because the Word of God declares it to be so, thus the cheating husband is as equally ignoring God as the person seeking a lesbian sexual relationship.  All sin is an affront against God, if the Church has failed to make clear its opposition to ALL forms of sexual sin, especially our own, that is our failure.  If Christians have seemed more interested in opposing homosexuality than in helping the people of the Church overcome adultery, that is also our failure.  We, the Church, have failed in this arena, far too often.  Holiness begins at home, the people of the Church have failed to live sexually pure lives, for this we need to repent and return to being what God has called us to be.  As a people redeemed by God, we cannot pretend that sin, of any kind, is ok.  It won't be popular to say so, and we shouldn't expect those who don't believe in God to be happy to hear it, but God loves you too much to ignore your sexuality, and as imitators of Jesus Christ, so does his Church.

My words are primarily for myself, my family, my church, and beyond that, the greater Christian community.  If they spur the people of God toward self-examination, and greater efforts at holiness (by God's grace) they will have achieved their purpose.  If my words speak to the Lost, to those without God, let them hear me clearly: God loves you, his Son died to set you free, God wants you to come home to him, whatever your past, whatever your present, God can and will forgive you if you put your faith in him.  When you do believe, join a local church, it is the place where the people who were lost, but now are found, gather together to celebrate God's mercy and grace, and to share his love.

Genesis 1:27 "So God created man in his own image, in the image of God he created him; male and female he created them."

Genesis 2:24 "For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh."

Mark 10:8b-9 "So they are no longer two, but one.  Therefore what God has joined together, let man not separate."

Matthew 5:28 "But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart."

1 Thessalonians 4:3-8 "It is God's will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control his own body in a way that is holy and honorable, not in passionate lust like the heathen, who do not know God; and that in this matter no one should wrong his brother or take advantage of him.  The Lord will punish men for all such sins, as we have already told you and warned you.  For God did not call us to be impure, but to live a holy life.  Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit."
