It's been a long time since I was a newbie to BJs, so I can only give you a thought on the sore jaw thing. The jaw is run by muscles, so it stands to reason that the more you practice and stretch them the better it will get.

For the gag reflex; if you don't already, close your lips! If I hang my mouth open like a porn star, I'll gag every time, but if I work on getting the lips closed it works much better. This too will take a lot of practice if he's very well endowed, but doing it that way seems to let his prick press and glide more along the tongue instead of aiming straight for the gag trigger spot. Go slow, concentrate on relaxing, and experiment with adjusting your head to different angles so he goes down the throat easier.

You might want to consider practicing on a dildo when he's not around too, because that will take the pressure of wanting to hurry up and please him off your mind while you're figuring out what works best for you.

Hope that helps

Position also helps, my favorite and most effective is me lying on my back with my head hanging over the side with b/f standing. This is an awesome angle. And yes, practice with a realistic dildo like a VixSkin (using the same position). If need be, you can fake how much you can take by having a well lubed hand and cupping his cock near the base as you take him off. less

For taking a cock deeper: I've found that I've decreased my gag reflex, or at least moved "that spot" back further in my throat over time. I did this by brushing my tongue (while brushing my teeth) every time I brushed, always as far back as I can stand. If I gag a little over the sink, it's not a big deal. I get used to having a "foreign object" back there, and I get to see what spots trigger the reflex the most (all while getting a minty tongue and throat, lol). Give it a try for a few days or a week and see if it helps.

For the jaw aching: I think Michele has the right idea with the closed lips. You can also stretch your jaw more often if you want to be able to open your mouth more comfortably. Chewing gum more regularly might also work out your jaw muscles comfortably without causing pain, which could help your muscles get accustomed to more use. less

I have big teeth and a very small mouth, which makes dentistry and blowjobs difficult for me. Honestly, my respite is just to use my hands as an extension of my mouth more, and to make up for it with plenty of tongue and different techniques, like licking from balls to tip then kissing the tip, or playing with a guy's ass while I blow him. less

I do close my mouth whenever I'm getting him off. He doesn't have me go down on him to get off, though. Just for extra foreplay before sex. All it does it tease him. I want to be a more effective teaser, though

I will try to focus more on my mouth, though, and go slower when I am using my mouth on him. Maybe that's what's wrong. We're both going at it all hot and heavy and not taking our time to enjoy it. Thanks!! less
