What are good foreplay moves to use on a guy?

Most men like the unexpected. If your man is watching tv and you walk in front of it nude, he'll be happy, but he already knows what he's getting. On the other hand if you know your man well enough, there are many way to experiance foreplay. Start with a mixed signal. (Sit beside him and "accidentally" graze accross his lap.) A little later, do something you know he likes (lick his ear, give him a peek when others are around, but noone else is looking,or give him "the look".)
Then hit him with a surprise. (Start somewhere other than the bedroom, or you do all the work for a change, or do something he's been asking you to do for a while.)
