These are the occasions in which you should listen to these songs during sex:
In Your Face: Would be a good song to listen to while getting a blowjob.
Next in Line: Fits well if you're at a gangbang.
The Nail: Describes the act of sex itself, so play during any regular/casual sex.
Punch Me I Bleed: Play if you're having sex with a sadist or you're both into BDSM.
Oops I Did It Again!: Play this song after sex if the guy you're with is a premature ejaculator. (Or if you wake up next to a really ugly bitch and didn't use a condom)
She Is Beautiful: Song must be played if you're drunk as fuck and about to bang a fat/fugly chick you picked up outside the bar.
Silent Night, Bodom Night: Play this song if you were about to have sex, then you fucked it up and pissed her off, and then got no play.
Sixpounder: Play this song if the guy has a really big dick.
Somebody Put Something In My Drink: MUST be played for PURE AMUSEMENT during date rape.
Taste of My Scythe: Another blowjob song.
Lil' Bloodred Ridin' Hood: Play this song if you're raping a preteen on her period?
Are You Dead Yet?: Must be played if you're both practicing erotic asphyxsiation.
