No man has ever done this. It's impossible. Sexual orientation is not changeable. Men who appear to do this are closeted and then they come out.
Gay men do not become eunuchs. Eunuchs were an element of some societies in Africa, Asia, and India, but those that chose to become Eunuchs may have been gay or straight.
No straight person becomes gay. Ever. You are either born gay or you aren't.
Sexual orientation is a complex aspect of identity that is generally believed to be determined by a combination of genetic, hormonal, environmental, and experiential factors. While it is possible for individuals to experience shifts in their sexual orientation over time, it is not a conscious choice. Therefore, a straight man cannot simply decide to become gay.
No. Gay men have just as much value in society as straight men. In some cases, more so, because some gay men adopt the children that straight men abandon.
Gay men are individuals who are attracted to other men romantically and/or sexually. Sexual orientation (being gay) does not influence someone's gender identity (being a man). Men, whether straight or gay, identify as male based on their self-perception and expression.
You can't. Sexual orientation is natural and unchangeble. You can't "become straight again" because if you are gay, it means you never were straight. What you can do is learn to love yourself.
if straight people look gay, its because some women like men that act like that, if they are gay and look gay, then they are gay...
Probably for the same reason that some Straight men talk funny.
Most men (gay or straight) become aware of their sexual orientation when they reach puberty. Women may also become aware at puberty, but some may take longer. For some women, this can awareness can occur well into adulthood.
Straight men generally do NOT chase gay women unless they don't know the woman is gay.
no, but it's possible that closeted gay men who pretend to be straight might do this.
Gay men are already men.
