A very forward crossword

"Crosswords won't cut it", announces the SMH. "orgasms are key to a healthy brain".

Well now. Depends on the crossword, dunnit?

 CLUES:
1. Ooh! Sings twice! Saucy!
2. Take a roll in the hay, right?
3. What did the two chaps have behind the milk bar?
4. Ice sex, minus one, is becoming to officials in short.
5. Close draw for pyjamas! 
6. It takes this to tango.
7. A low slip for bed clothes.

Unfortunately I'm too young to know the answers, or I'd tell you them, for sure.
