As far as sexual content goes, I'll refer to a line in Beetlebum. This was a cover so it could have been censored or changed if HMX wished.
"She'll suck your thumb, make you come"
And as had been before quoted, from I Wanna Be Your Man.
"You better pray you live to see another day after the way I'm gonna punish your ass"
And I don't think I even need to quote some of the Spinal Tap lyrics. So sexual reference is pretty open enough, direct sexual content likely not so much. damn seems to be fine on it's own, however a god placed before it will throw it up in the air, so it's best if an edit is used to take out the god. F-bombs are a big no-no I'd say, and with the entire political correctness thing going the way it is I'd say pretty soon N-bombs will likely be banned from media altogether.
Drug references etc. should be fine, I mean there is The Perfect Drug. I'd say if drugs globally are allowed to two centric ones should be fine too (Tobacco/alcohol).
S-bombs would be a no-no, but crap should be fine.
Hell I'd assume would be fine.
A-bombs should be okay, assuming you don't add an H-suffix.
B-bombs would depend on context.
As for C-bombs... I think that's pretty blatantly a nono.
