Me too.
Actually, more of the people we know may be gay than we realize, especially if we haven't met their partner.
Even today gays in some locations, professions, religions, and families may have good reason to stay invisible.
Next, tragically some men married to women are closeted gays who have sex with men in public restrooms and gay bath houses.
Until a couple generations after the day arrives when there is no social stigma about being gay we'll never know what percentage of the population is really gay.
