At what age did you first realise you were gay or bi?

[Karl Rand]

I was fascinated from a very early age (4?) by an athletic man in speedos who sunbathed on the beach in front of our house. I didn’t know what gay was ( the word wasn’t being used then) and certainly had no idea about the ‘facts of life’.
I knew I was sexually attracted to both males and females from about age 12. Somehow in my early 20’s lost interest in the female of our species. (apart from getting very stoned and lapsing once.)
