Ok, being someone who engages in said kink. Here is my verbal coinage (2 cents):
First, and foremost- has he done play like this before? If not then the two of you need to sit down and talk about what does/doesn't excite you. You can be seriously hurt by someone who plays with items that they have no experience with. Look at websites that carry 'toys' of the trade, see what looks exciting.
Second, when you have explored and reached conclusions as to what you'd like to try... set some ground rules i.e. safe words... colors often work well red- stop what you're doing, yellow- ease up, and green- keep it coming. There is a common misconception that if you safeword, all is done, it doesn't have to be. It's just an indication for him to know where your thresholds are.
Third, if you don't have the time to peruse the web, then keep it light. Maybe some light bondage and the usual (I say that loosely) sex toys kept about. It's amazing what a vibrator feels like when you're helpless to squirm about *sighs dreamily*
Like Haru said, play safe. Practice safe sex if you both haven't been tested, but first and foremost, explore the kink slowly. Last thing you need to do is explain unexplainable bruising or cuts because of being careless (not intentionally, but playing with a implement that he has no experience with).
Have fun and explore away!!!
