I don't know where you're from but I attended urban black schools. Most of my peers had lost their virginity by the 7th-8th grade. I lost mine at 16 and felt like I was years behind. But that's hood culture, prolly not the norm.
Either way, if it's 11 or 17 I'd rather catch my son smoking a blunt than sucking off another boy.  The only thing an 11 year old needs to know about sex is that they're supposed to wait for marriage and have children.
But if y'all want to follow behind cacs and pretend like little boys can decide they like dikk or want to gender swap, don't say shyt about people who let their kids "decide" to smoke weed.
		
		
	 
I’m sure any father (hell I would, too) rather their teenage son smoking weed than being attracted to guys. bad crowds, smoking weed, skipping school etc is a lot easier to deal with than being able to fix/change a person’s entire sexual orientation (something I still don’t think is possible.

 In a perfect world yes, but the reality of the situation is that a big part of the journey that is adolescence is puberty and the changes that it brings.. 11-12 is around the time these kids first start to actually process their sexual preferences even if they don’t act on them yet, some of actually start fukkin in 6th/7th grade like u said, so I can imagine that a gay kid knows he’s gay around that time too and just keeps itunder lock and key until later.
Parents can decide not to let their kids smoke weed in the same way they can forbid their gay children from dating or acting on their impulses/affections until they’re out of the house.
