I did tell you how I believed it. I gave a few examples. For instance, if a guy with gay feeling principally and voluntarily decides not to give in (actionwise) to his gay feelings, how gay is he? To me... he's not gay. He's a guy struggling with his sexual feelings, to me it's no different from anyone else struggling with his sexual feellings. Compare it someone who doesn't get satisfaction with his partner and likes to have various sexual relations. Now, having more than one sexual partner is accepted these days, but if this person values the relationship with his partner so much and does decide NOT to go into it, he wouldn't be called a guy who sleeps around, even though he has the desire to do so.
What does your dictionary say about such cases?
It's not so much that I diagree with you. It does depend from what side of the coin you look at it. In case of my 'gay' example above, such a person may not even like to be called gay, he might find it offensive. So what do you do? Throw a dictionary at him?
