I agree that its about a sexual encounter. I have a theory though, that the 'hot wax' is referring to a condom.

"It's a pool of boiling wax, I'm getting in (Putting on a condom) Let it set Got to seal this in (self explanatory ;) ) Can't adjust, Can't relearn Got to keep what I have, preserve"

"Hot wax has left me with a shine Wouldn't know if I'd been left behind (feeling is minimal, and wouldn't know if she's come before him) Second skin, second skin" (If anyone has ever put your finger in melted wax it feels like a second skin)

"I can't let it out, I still let you in" (she can't let him in her without the condom on, but she still let him in at all)

I may be clutching at straws... it was just the hot wax/second skin thing that made me think of it.
