Use your tongue. You cover your bottom teeth with your tongue and don't allow your top teeth to scrape his skin. If you use your tongue correctly, you should be able to angle his junk away from your teeth. All he should feel is the roof of your mouth, your tongue and your lips. I use my teeth gently on my husband just to give him variety - though some men do get sensitive about teeth being that close to their precious jewels.
Practice with popsicle - I hated scraping ice with my teeth so I learned quickly.
Good luck.
WELL ITS VERY SIMPLE...U HAVE TO OUT HIS COCK SO DEEP INTO YOUR MOUTH THAT IT IS HITTING THE BACK OF YOUR THROAT BOB YOUR HEAD UP AND DOWN. YOU WANNA SUCK IT THE SAME WAY YOU WOULD ENJOY AN ICE CREAM BAR. MAKE IT REAL SLIPPERY BASICALLY YOU HAVE TO DEEP THRAOT AND SUCK WITH YOUR LIPS, YOPUT YOUR LIPS OVER IT THE WAY YOU PUT YOUR LIPS OVER A LOLLIPOP
Its not as difficult as is seems. When you suck a guys cokk, just suck with your lips, get into it without worry and your teeth will not get in the way. I have never felt a girls teeth on my cokk before. I guess it could happen, but don't worry about it. Give him a nice suck and he will be so happy. Oh yeah, your tongue will be rubbing it too.
If you can eat a lollipop or an ice cream cone without scraping it with your teeth, you can do this. It's the same thing.
