While the logistics of shower sex itself are a bit dicey (and dangerous), there's nothing steamier than soaping each other up in an overheated shower stall when it comes to foreplay.

But sometimes -- despite how much you flutter your eyelashes as you say, "I'm just going to pop into the shower" -- your houseguest just doesn't get the hint.

You can be direct, and simply ask him to join you.

Or, if you're as socially retarded as I am, you can be a bit more subtle and pick up this emoticon shower curtain. All the winks, smiles, and flapping tongues can do your flirting for you.
