Bllack girls: Do I wear tighty whities and what is the difference?

-I am a junior in high school. I like to wear the white fruit of the loom and hanes briefs. Do most guys wear briefs? My brothers told me that guys my age don't wear them anymore. Is my kind consider tighty whities? Why do girls despise them. I want to sag with them because most girls think its hot if a boy sags with boxers. Is it okay for a 17 year old to wear them? I cant stand boxers at all also. If i have to, How could I convert? Is it unhealthy for boys over 13 to wear them? I really don't want to get made fun of also in the locker room by other guys. I am in love with someone also. Also I like to wear the captain america briefs too.i think its tacky when boys sag their jeans below there butt and show there boxers
