"I have no proof, but it seems to me the correlation much surely be significant?"

Uuuuh NO.

In my experience not even half of the BLs I have talked with had a sexual relationship of any kind with an older person when they were prepubescent. I had no sexual contact with anyone until I was in jr hs and that was someone my same age. It was a GIRL. I am a BL.

Having sex, whether it is a positive or negative experience, does NOT change your sexual orientation no matter your age. For example, Cat has had sex with his wife I assume. He is still a BL. IF age mattered than EVERY boy who ever had sex with a man would be a BL which is not true.

If I thought having sex with a boy would make him a BL it would make me consider it as a factor but it is just not true.
