We humans have a nasty habit of being prohibitive, especially with respect to sexuality. Our cultural norms are pretty hard to shake, so something historically frowned upon can maintain inertia long after the underlying motivations of the norm are shown to be flawed. My view is that morality and ethics are underpinned by what improves wellbeing and/or reduces suffering. Offense to our sensibilities is no cause to prohibit something. If 2 or 3 or 19 people are engaged in a relationship or activity that is preferred by those people and is not harming anyone, then other persons should stay out of it. If someone is forced or coerced or otherwise harmed then that person should be protected. But what people choose to do with their bodies "neither breaks my leg or robs my purse" as Thomas Jefferson once said. I'd like for humanity to stay out of people's lives. We each have roughly 80 years of life. Anything that interferes with someone's personal, non-injurious decisions is unethical.

Whether it is a choice or not (Even though science tells us that it exists in nature and it has a genetic predisposition), its not my right to judge them for it and so none of my or anyones god dammed business.

I could not give a flying flip about someone's sexual orientation.
