There is nothing wrong with the term "sexual preference". I am male, I love women, that's my sexual preference and I was probably born with it, if not, I developed it while growing up. But here it the truth: No one is able to choose his sexual preference. Really. Try it, you will fail, be assured, you will not enjoy the experience. So, if a man finds out that he loves men, or a woman finds out that she loves women, it is the recognition of a personal trait as one recognizes the colour of one's hair. At least it should be, if everyone would see the things as they are and not make something up. That there are people who do not accept that law of nature, that is the real problem. And worrying about words won't help here. Telling the truth might help.
And whatever someone is or does and enjoys it, as long as it does no harm to someone else, everyone should be happy with it. God is.
