If you ever had a dream that you were getting a BJ and you look down to see that it is a guy giving it......then you are less than 100%. IMO.
I think it would take a lot less than that to be less than 100%. Just being aroused by seeing or thinking about a BJ makes you less than 100% IMO.
But really, even a spectrum based on percentages is a far too simplistic way to define sexual attraction.
It is the sex act and your imagination placing yourself in that situation that is arousing not the other guy's wiener, good grief.
What is your percentage Mich? Feeling attracted to another man, not your weird redefining to suit your own purposes.
