How'd you feel about a situation where you founding out that your little brother or your own son was penetrated by a dude after he seduced him?
Sorry dude, but your "little brother" is gay
If you got seduced into having sex with a man, you are gay... that's obvious right?
I'm personally not gay, and there is zero chance of me being seduced by a man... it wouldn't happen...
I think gay people are awesome, but I wouldn't have sex with one... I'm just not attracted to men... my penis doesn't get hard or anything... it couldn't happen if I tried
That being said, your brother is gay as fuck if he had sex with a dude
Your best bet is to love him for what he is rather than hate him because he isn't what you want him to be
