Where you wearing the **** ring she got you???

Vaginas don't have many nerve endings in there (because you know babies) and you probably weren't doing anything for the clit, doggy is a position many people don't like for that reason. Although I have to say not feeling anything might just be falling asleep from staying in the position too long.

Either your dick is tiny or she is a loose ***** for your sake I hope it's the second.

Hope things look up in the future if all else fails growth pulls might help...

Adjust the angles. Make sure you slide along her G spot and put pressure on it. And slow down. You need that tempo for the home stretch.

She could be really loose.

Well someone's not a virgin, or someone isn't doing it right.

Wow, i guess you screwed her until she's numb.

First comes the laughter, then comes the tears.

Don't worry OP, these things are typical when you get into very rapid "successions", you may not be too small, and she may or may not be too loose, the amount of wetness she creates can always be a sure sign of losing feeling. Maybe you guys need to slow down and be more methodical in your act. I've been down the same road and it was neither of our faults, well., I guess you can say its hers, although she doesn't control the flow of the river.
