There is at least a time component to consider, as you might feel gayer some days than others. It likely also depends on you company, that is, if you are around a lot of hot men who are open to the idea of gay relations but not many hot women interested in you, you might feel gayer than if it were the other way around. So by sorting the population you would skew the amount of gay in a population by grouping gay people around gayer people and not as gay people with their kind.
