I think that we are all born unique. Some types are “prone” to gayness- i.e. passive or effiminate men and dominant powerful women.
If you’ve ever experienced youngsters you know that they show early on the personality traits which they’ll carry for life.
I think it is chemical. I say this because while I’m athletic and fairly aggressive, I’ve never had the “killer” instinct. After taking prednosone (steroids) for an injusry, I “got it.” I understood how the bad asses must feel. I felt like I could but my head through a wall- and I WANTED to!!
On the other hand, four of my good friends - men who are completely hetero, with strong, long marriages and children - have effeminite characteristics. Two of them are fellow Air Force Reserve colonels.

My experiences with lesbians are that they typically hate or fear men, not that they're necessarily dominant or powerful.
On the other hand, many dominant and powerful women I've known (and I married one) are definitely heterosexual, and confident, enthusiastic lovers.
I think it's hate and fear that turns women lesbian, not strength.
