There are still many unanswered questions about sexual orientation, some of which seem (to me) to be urgently in need of answer. For example: Researchers in the Netherlands found that a gay man who is in a relationship with a gay man is eight times more likely to commit suicide than is a straight man who is married to a woman; by contrast, a lesbian woman in a relationship with a lesbian woman is no more likely to commit suicide than is a straight woman who is married to a man. The researchers point out that the Netherlands is one of the most tolerant and accepting countries in the world for gay men and has become even more tolerant and accepting; but in this study the younger men were at the same high risk as the older men. There has been very little research directed to understanding the reasons behind this finding.
