Other recommendation is to explore gspot stimulation with fingers/toys and anal stimulation if she is into it.
Ultimately though don’t worry too much about this if she says she is satisfied. But the lack of clitoral stimulation could require some medical investigation. Something like her hormones could be off.
I’m just starting to think humans crave conflict. The larger the population and the more interconnected it gets the more we need larger scale chaos. I’m worried the only solution is to satiate that desire through global war. It’s so depressing to think about.
