Sexual Orientation: Nature or Nurture?

Still an ongoing controversy today, does one's environmental raising or their genetic traits influence their sexuality? I, myself, personally believe that one is born with the sexuality they will lean toward when old enough to make the choice. There are many who will debate that a person is taught to be homosexual and they could change if they wanted to. I do not believe this or see how anybody could think it possible. Why would …

…family of five siblings who are homosexual. These children were raised in a normal healthy environment by two loving parents, went to church, and were shielded from most negative influences. So how did three of them turn out to be "normal" and the other two not? This is why I personally believe that one day they will discover that there is some type of genetics that determine if a person will be homosexual or not.
