I have tried doing the same - all the men I have slept with can be divided into two camps... but I met my ex when I was 19 I simply do not have the experience.

but my lack of experience did not stop me from instantly thinking aha, he is talking about sexual orientation.  That magnetically attracted or repulsed element.

It's interesting how our parent's generation was so enamoured of Hemingway's masculinity.  The quote I remember hearing some years ago was him saying that writing was to sit at the typewriter and bleed through his fingertips.

From the bit of reading I have done I think it likely his mother was gay.  And using pure imagination I wonder if he was straight but married a gay woman and that is what led to a son that went from Gregory to Gloria.

see what I mean about that quote - it really does set the cat among the pigeons.  and that's before we even get to the love slave part!
