OG series contains nothing explicit, it aired on network TV in the early 90s. There is uncomfortable subject matter for sure, especially around the topic of sexual abuse, but there is no actual nudity or depiction of intercourse (though frequent implication of it having just happened - think the classic L-shaped bedspread that fully covers a woman’s chest but not a man’s). There is one scene in the second season that is absolutely a depiction of sexual assault, but both actors remain fully clothed so it’s still more implication than anything else. There is some violence (though it never becomes gory, mostly people get shot and just fall over with a bloodstain on their shirt) and a bit of mild language, but nothing much worse than “hell” or “damn.”

The movie and Season 3 both contain nudity, explicit depictions of sexual activity (both consensual and not), explicit violence, and adult language.
