Washington, you actually have it backwards--a person's thoughts and intents are what makes something good or evil, not the physicality of touching. If I kiss my daughter with the intent to express love and affection for her, I have not sinned. If I kiss my daughter for the purpose of sexual arousal or to gratify a prurient sexual interest, I've sinned. The act of the kiss itself is neutral with regards to good or evil.
When it comes to sex, the only healthy and moral form of sex is that between a man and a woman who are married to each other. All other forms of sex are evil. When a person engages in an evil form of sex, the evil aspect of that form of sex becomes exciting and sexually stimulating. A person who has sex with a stranger will find the fact that the person is a stranger very exciting and will often try to pursue the experience again. If that person gets married, they will not be having sex with a stranger anymore, so sex with that person's spouse will not be as erotic and exciting as it should be. So the married person will desire sex outside the marital context, which may lead to extramarital affairs, causing the destruction of the marriage.
If a person finds themselves attracted to the same sex, the worst thing they can do is to gratify that passion, just as a person who has sex with a person not their wife has made a serious error in judgment. Basically, we have two dogs in the kennel--a nice dog and a vicious dog. If you're constantly feeding the vicious dog, the dog will only get bigger and more vicious. Eventually the dog will overpower you and kill you. You gotta stop feeding the vicious, addictive dog.
Homosexuality is nothing more than an addition, just as cigarettes or drugs. People also get addicted to sex with strangers, sex with children, sex with animals, inappropriate contentography of various kinds, etc. We all have different proclivities to certain types of addictions. Some people can take pain killers at hospitals and go home without getting addicted. Others will find themselves consumed with the desire to continue using the painkillers and sacrifice all their money and their entire lives to get their next fix. Some people never get the desire to have sex with people of the same gender, some do. If we have a desire to engage in an unhealthy addiction, it's never healthy to feed that addiction. Feeding the addiction only makes it worse. All addictions separate us spiritually from God. I myself am actively fighting certain addictions.
Homosexuality is one of the worst addictions. It goes without saying a person's bowels are not designed to accommodate the insertion of external objects. As a practical matter, it's a very unhealthy and ultimately unpleasant form of intercourse.
http://www.conservapedia.com/Gay_Bowel_Syndrome#_note-93 A person who is consumed with homosexual sex will be less likely to be married and have children, which I have found to be very satisfying and fulfilling. Many people find it very sad to be over the age of 50 and still not have a family. It makes life, especially around the holidays, very lonely. Homosexuality ultimately causes death. In San Francisco, homosexuals acquire AIDS at a rate of 2.2% per year. By multiplying 2.2% by the number of years a person engages in gay sex, you can get a rough idea of how long it takes that person to get AIDS.
I mentioned that homosexuality is an addiction--it causes sexual desire to boil over and become extremely difficult to control. You can read about homosexual lifestyles here:

"In their study of the sexual profiles of 2,583 older homosexuals published in the Journal of Sex Research, Paul Van de Ven et al. found that "the modal range for number of sexual partners ever [of homosexuals] was 101-500." In addition, 10.2 percent to 15.7 percent had between 501 and 1,000 partners. A further 10.2 percent to 15.7 percent reported having had more than one thousand lifetime sexual partners."
The result is that homosexuals become epidemiological locus points for disease transmission. If most people have only a few sexual partners, a sexually transmitted disease will peter out. It only takes a relatively few people with a vast number of sexual partners to become an engine for the transmission of diseases through a population. This makes homosexuality a matter of public policy. It's not simply a private matter if people can't control their sexual urges. That's why the Bible bans homosexual intercourse.
That said, God loves homosexuals as much as everyone else. All sins are equivalent in God's eyes--addiction to caffeine and addiction to homosexuality are equivalent in God's eyes, though their practical consequences are considerably different. If a person is willing, God can and will save them from their homosexual desires.
