1. Grab his hair and guide him. **Pretend his hair is a steering wheel and you're driving his car-head straight to Pleasuretown, AUS. Maybe don't actually think about that in the moment so much, but use it to guide him up and down, and increase or decrease pressure. Bonus points because guys think it's hot.
- Make it obvious when he's doing something right.** Play it up a lot when he's doing things right, and don't be as loud or enthusiastic when he isn't doing what you need. Think of it as a game of "Hot and Cold" but with your clitoris. For the record, this is the most passive-aggressive way to do things and will probably take a while before you see any real payoff. But if you're a passive-aggressive person, this is perfect.
- Be more adventurous.** Start introducing new sex things into the bedroom every week. One of those things can be your vibrator. Don't throw it in the mix right away. Maybe do a blindfold one week or some handcuffs the next, then introduce your favourite, tried-and-true sex toy. Alternatively, you could just be like, "Yo, use my vibrator when you go down on me."
- Watch porn together.** Pop on some porn and copy it (just make sure to screen it in advance so you know it's positions you like). He'll think it's hot and he'll have no idea you're really using it as a cunnilingus class for him.
- If he's not doing it enough, just ask him to go down on you.** Does he not cover foreplay for long enough? Do you need foreplay to warm up? Tell him. If he tells you he isn't "into" going down on you or that he just flat out doesn't do it, then tell him to fuck off.
- Tie him up (but run it by him first, obviously).* With his consent, dominate the hell out of him. All of the sudden, your suggestions become part of an elaborate (and sexy) game. Everything you were worried about being misconstrued as mean or bossy takes on a whole different context. Put on your sexiest underwear, give him a few spanks, and 50 Shades of Give Him Explicit Cunnilingus Instructions your way to an orgasm.
- Ask him to spell the alphabet with his tongue. **This one is tried-and-true. Have him trace each letter out with his tongue. Stop him when he reaches a letter that works for you. Ask him to always do that letter forever.
- Put a pillow under your butt. **You'd be surprised just how different it can be with a slight raise in elevation for you (and easier access for him). It might just be that he has a tough time on his stomach wedged between your legs.
- Straight up tell him what works for you.** If you don't know what would work better, masturbate more to find out, then tell him your findings. If you feel bad about dissing his skills, say, "Hey, this used to work for me, but recently it hasn't been. Can we try something new?" You won't regret bringing it up.
