I think you can settle any doubts on pure homosexuality by asking one simple but direct question:
Would you bang Scarlett Johanssen?
If you don't, it's settled, for once and for all. You are a Kinsey six. Scarlett is the true yardstick to liking women: if you don't like this one, it's unlikely you'll like any other. I know of no man who doesn't want her in his bed, even a nominally gay guy I know almost drools over her. Scarlett truly brings out the bisexual in the queer.
Sorted. I'm not a Kinsey six.
