He must be doing it for a really long time. Lucky you.<br />
Mine has never gone numb, and I do like to use it for a long time. I think the answer is to vary what you are doing with it, gentle licking, hard flicking of the ****, poking it in the ***** or ***.<br />
The only thing I find with extended oral play is my jaw can begin to ache after a while and I have a tendency to cut the piece of skin that joins my tongue to the bottom of my mouth, with my bottom teeth.
Nothing goes numb. In fact everything feels more. Tired maybe but worth every second.
Mine has on several occiassions and it sometime takes over a week to go back to normal. It does not happen everytime, yet when it does go numb it can be quite annoying, and if it takes two weeks to go back to normal. I have even thought maybe it may be some strong bacteria that gets deep into the toungue cells and only comes out after brushing and mouth wash over a period of time.
Mines has a couple of times but it takes a while for it to happen
It hasn't happened to me, but it could.
tongue not so much, but my fingers do cramp up and need to switch..
Only after a long time. Before my beloved & I met she had NEVER had an ****** (& she was over 40). Her first husband was just the self centered type, so she didn't really know how. The first one I gave her took a LONG time. I guess she had trouble relaxing. Yea I got numb & damn near got lockjaw...lol Once she did the first one though the rest came (pun intended) easy. Haven't been numb since. Now it takes maybe 3 min
So far mine never has and I love to do it for a long time.
Only in the 3rd hour it gets a little sore!!
Hell no, it doesn't! I LOVE eating *****! I will eat a ***** for as long as she wants me, until I have her begging for me to **** her!
Just as jackrabbit said, if you do it long enough it starts to go numb. It's something that gets better with practice, so get your man to saddle up ;-)
