I can't make you enjoy something you don't. But if you're good, giving, and game it won't hurt you to learn a few new tricks (and this may come in handy in other relationships years from now too).
Spanking: erotic play with impact DVD/book combo by Lolita Wolf (Dem-Lab S/M Tech). Available at Amazon. Video is so much better than books for learning this stuff. Plus with spanking you don't need to spend money on toys right away.
OSK Productions has a line of how-to DVDs (they have a website but I got the DVDs from CdUniverse); CBT, Rope Bondage, Suspension, Sounding, Puppy Play, FootJobs (a must if your BF has a foot fetish), etc.
Nina Hartley has a series of D/s themed instructional porn, but she doesn't cover anything hardcore, if you two are fine with fuzzy handcuffs and feather ticklers her stuff may be right up your alley.
If you have any specific fetishes or skillsets you need help with feel free to ask, but these should get you started.
Getting into the BDSM mindset can take awhile, but ask your BF to show you any porn or websites he likes (for his 'gentleman's time'), and try reading some FemDom books: She's On Top by Rachel Kramer Bussel or Hurts So Good by Alison Tyler. If erotic fiction isn't your thing and want to read BDSM nonfiction try My girlfriend comes to the city and beats me up by Stephen Elliott. If you have Showtime you can watch I can't believe I'm still single, or if you're really looking for something that'll stick with you, rent the documentary Sick: The Life and Death of Bob Flanagan, Supermasochist. Or if you can find it (Netflix used to have a copy) Fetishes: Mistresses and Domination at Pandora's Box Where the filmmaker spends a few weeks at the somewhat infamous NYC dungeon.
