I've been Tango'd

We you may remember I am a bit of a fan of the Tango , it seems to have taken over from most of the other toys we have ( and there are a lot) , but I have 2 question

After my better half has climax's ( cum finished orgazmed) she seems to be a bit numb down below is this because the tango is to powerful ? or just normal ?

secondly I love the power of the tango just wondering if there is a G spot vibrator with the same power ?

we have the r1 rends with a predator but its just a bit of a pain with cables batterys ect
