Whether it’s his birthday, Valentine’s Day, or simply Friday, give your guy a gift he won’t soon forget.

Giving sexual favors as prizes, rewards, and even presents can be a fun (and inexpensive) alternative to shopping. Try writing out a few naughty coupons for your lover to cash. Then, wrap them up in a big box. When he reads the words, “Good for Anything,” he will definitely not be disappointed. Chances are, he'll never forget another Valentine's Day.
