First post on here so here goes.
Basically, when performing oral on my wife she also enjoys a toy inside her. We have a range of vibrating dildos, but the larger ones only seem to go in to a certain point (6 or so inches) before she is in pain and says no deeper. She has no problem accommodating girthy toys, so it’s more of a depth issue.
As a comparison, I (average size - 6 inches or so) can go balls deep and for the most part (unless I’m at a funny angle or whatever) she has no issues or discomfort.
I know she is turned on when I’m using the toys and I understood that vaginas could normally lengthen to take any size, so am I doing something wrong with the big toys? I slide them in slowly!
