A lucid two-headed treesome

Hello Dreamviews members!
Today I have quit lurking the forums and am ready for my first post. I will share an interesting LD I had last night. It was a very sexual dream, but I will keep it nice and tidy here :)

I am in a gift shop surrounded by other people. In the middle of the shop is a bed. My girlfriend is already on the bed. I join her and become lucid by looking at my hands, I count way too many fingers so conclude that this must be a dream! I order everyone to leave the shop.
I am alone with my girlfriend and we start having sex. But she has two heads, one is her real face, the other a cute Asian girl. Then the dream faded away.

The two heads makes things pretty interesting!

One thing I wanted to ask. Those involved in relationships, to what point to you share dreams/lucid dreams with your partner? I'm usually pretty open about them, but feel that they sometimes lead to misunderstandings..
