I also experience a tired jaw. I've found that our positions have a huge impact on how long I can go. I've discovered that oral sex from the side tends to fatigue my jaw faster than other postions. Kneeling in front of him helps. So does just getting between his legs and sucking from the top/front. If your mouth/jaw still get tired from these positions, try just licking for a few minutes to give yourself a bit of a break. Most guys love or at least like the licking and are understanding. I don't know if you tense your jaw during oral sex or no, but if you do just relax it. That's all I can think of right now. I hope it helps :D

Practice, practice, practice! ; ) Other than that, I'll agree with the other answer here: use the most comfortable position you can find, which usually means lining up straight instead of coming at him from the side. (Penises aren't perfect cylinders; depending on his shape, you probably don't have to open your mouth as far when you're in front of him.) I've also found that it's easier to give head comfortably if he's sitting down and you're on the floor in front of him, which is great for fooling around outside bed; the best blowjob I ever gave was to someone standing up, but that can be less comfortable for him and depends on your relative height. Taking some time to lick or just suck on a small area (the head or balls, for example) also works well. I recommend doing that first, though--better to work him up slowly and then suck him off than to get him all fired up and then have to slow down.

Lying between his is legs works for me and he prefers it, suck, lick it, love it! dont wear ur self out, when ur tired kiss it lick it dont focus so much on swallowing the penis, use ur tongue and lips to explore his penis, to feel all of it, he will enjoy it, keep payin attn to the head, shaft, and balls, when ur jaws feel relaxed again, get back on that penis full force! have fun!

WELL, BY EXPERIENCE A COMFORTABLE POSITION FOR ORAL SEX WAS TO LAY HIM ACROSS THE BED AND GET ON UR KNEES ON THE FLOOR. YOU CAN ALSO FOCUS MORE ON THE HEAD, TO PLEASE HIM MORE. SUCK EVERY ONCE IN A WHILE BUT TAKE BREAKS TO LICK THE BALLS AND THE HEAD OF THE PENIS. AND HE'LL LOVE U !!

You must practice. On your guy and maybe just with a dildo. When your mouth starts to get tired , just lick his penis kiss for a small brake and then continue to suck on it. You dont want to be really close to the climax and then have to stop and restart!

I agree with you all there is no better way than on your knee's,you will fill and see that he really love's it and if you see that he is loving it you too can climax off sucking your man dick.

well being that i love performing oral sex to my boyfriend also i happen to have gotten really good at it...i used to get tired also but you gotta know how to realx your mouth. dont just stroke up and down cuz of course your cheeks are gonna get tired. do the head for a while as if you were sucking on a lolipop...dont go any more down than the head...while sucking on his head only you can use your hand to stroke the rest of his dick (this will help him cilmax even faster) let go of your hands after you stroked him a little and then just work with your mouth...if you get tired again go down to his balls, guys have a sweet spot there too. lick them and suck them (not too hard) and play with them...you can also stroke him with your hands while sucking on his balls. keep doing this and you wont het tired... when ever you feel tired just move up to his head and stroke with the hand....feel free to also just jerk him off and have him tell you when the good stuff is cuming so that you can catch it. lol good luck and let me know how it goes

It is a real turn on for my partner to lick my balls rim my cock had, slide her tongue up and down my shaft, put her tongue in my sum slit, nibble on my cock head, lick my balls and play with my g spot as well as massage my cock where it goes down below my balls. I love it when she sucks for a while and then doessomethign different, also take abreak and hve him give your oral sex nd try 69 all are a real turn on my partner nows when I'm ready to cum by the way my cock gets ragging hard and my head sweels, thats when you allow him to slide all the way in and cum. Enjoy, its a great way to have sex! for both of ya!

use your hands for a while and other things to give your mouth a break learn to deep throat that'll make him cum quicker!

Great head is a process. 1- getting him erect. 2- getting him excited. 3- Stimulating other parts of his body other than his penis. 4- stimulating his mind a bit by dirty talk as you use you hands. 5- using you mouth and tongue to tease. 6- use your breasts to rub his penis on your nipples or give him a tit job. 7- Finish him off with your mouth. By this time your mouth should not be tired and he should be very close to orgasm. Use your hand while you talk dirty and tell him how you are going to suck his cock and let him cum in your mouth and that you love the taste of him and his hot sticky cream.....then start sucking. If your jaw or mouth tire go back to that talking jerking thing. Use your breasts for a tit job or rub the head of his cock on your nipples. Even smack yourself in the face or breasts with his cock. Suck on the head while jerking him off. Or lick the bottom part of the head were it is most sensitive. Do blow pops with his cock. Remember them when you were young? You did them with your finger. It's a little different but similar, experiment. With your other hand cup and play with his balls, massage the area behind his testicles were his prostrate gland is, lick your finger and use it to play with his anus or insert it if that's what he likes. Have him stand up and use both hands on the cheeks of his ass, squeezing them while you fellate him. Use everything you have in terms of your hands mouth and mind. Some men have a foot fetish and you can jerk him off with your feet too. Just use whatever you have, some men even like a vibrator on their prostrate, that has been know to really do the trick. There are also books on the subject.

TALK LESS!

thats easy, take a break from your mouth and let him pump your pussy for a while.

i think that its your lotion and maybee you should try a new kind. Make sure to apply a small amount on your penis and see if it becomes irritated. If it does then try to find a new one.

Suck it like you want something to come out, like one or both of his nuts....

Don't hurt yourself. Just stop when you start to get tired. You can always just finish the job with your hand, or have sex
