Dear confused, it sounds like you are about to embark on one of life's great adventures. To begin with, you have no need to pretend that nothing's wrong, since nothing is wrong. You are one of the very fortunate women who have large, lovely labia. Those inner labia hanging down between your legs are something of which to be very proud. They are a sign of your sexuality. Enjoy them. I hope you play with them yourself. As far as your b/f is concerned, just tell him what you want. That is, if you want him to perform oral on you, just say so. Tell him how excited the thought of it makes you. Ask him to lick those beautiful lips of yours, to suck on them and play with them. After all, that's what they're there for. You are blessed. Act like it. Enjoy them, and your b/f will too. If you decide to discuss your labia with him before hand, do so from the point of view of how excited the thought of oral sex is to you, of how excited you get just thinking about this or that thing which he can do for you. Keep the discussion positive and exciting. Put aside your concerns adn insecurities. As you can see on this site, men are seriously attracted to longer, more full labia. You are fortunate to have them. Your b/f is fortunate that you are considering allowing him to play with them. Best wishes to you both.
