I have only heard one thing about making sure you're trimmed- make sure you're trimmed! There's nothing worse then going down on a guy and coming back with teethful of pubes. Start in the shower- lather up everything down there with some unscented, mild soap (I say unscented because if your pubes smell like Irish Spring I really don't want to get my face all up ons). After you've thoroughly washed everything, towel dry and then use a small pair of scissors or your beard trimmer to maintain your bushy... well, bush. If you're *really* adventurous, try shaving (tho the stubble is a pain to deal with after) or waxing- I LOVELOVELOVE giving Martel head when he's all smooth (and I love giving head no matter what!).
Also, talk to your woman. This might be a good oppurtunity to communicate with her about what you both want in sex- I know Martel and I have "sex talk" about once every two weeks- just to get feedback on how we're liking it and what we want to change, if anything. Let her know that it's just something that feels good for you, and you'd like to explore other ways of being intimate other than just having sex (I mean, handjobs before work, you going down on her as soon as she gets home, long massages followed by long mutual masterbation sessions, that sort of thing.). Good luck
