If you don't feel comfortable trimming don't. You'll only find yourself feeling naked and itchy and the oral sex is supposed to befor your pleasure, eh? Be responsive to his needs but try to keep your health and comfort in mind first. I find the wiping myself down with a fresh clean wash cloth can be comforting before sex if I've been very active or pee'd alot. I wouldn't personally use baby wipes for fear of scents, oils, etc causing irritation, but some people swear by them.
