Help Please

I'm 8, and wondering when I should প্রদর্শনী my parents PSG. We say shit like it's hell, and fuck is okay. Dad never talks about sex but Mom sometimes talks about it, like when she told me how শিশুরা were made. But especially about দুশ্চরিত্রা Girls. That one is very sexual, but still is pretty fucking awesome. So yeah. Please answer.
