Pink is the New Black

or something.
Okay, my story:
She had just moved across the country from everyone she knew and loved. She's given a chance to make some friends, but rebuffs them. She chases her cat, and ends up in another world. To escape this world, she must team up with beings she's never seen before and fight creatures she's never imagined could exist.

So, that's the "prewrite" beginning, but I have a question for the middle. It's a romance. So, there has to be sex.
The world she ends up in is Faerun (Dungeons and Dragon world). She's helped by the man she rebuffs. Well, his character anyway.
My question: safe to have sex? See, I'm still not sure if he's going to "remember" what she remembers or not. Maybe she'll just chalk it up to a very erotic dream?
Ideas?
Please. Anything. Seriously.
Well, no mocking :D Not that I think anyone would :D
