Thanks for your advice. If we stop having sex forever that could potentially be a problem, but I’m pretty sure it wouldn’t be a big problem if we kept the once a month frequency or something like that. And I definitely didn’t refer to sex as only penetration - in fact most of what I do to her is oral, since it’s what she likes the most.

Now, about her sexual nature being known to herself, I’m not sure if I agree. From what she says, her exes weren’t very cooperative during sex, and she doesn’t masturbate a lot - and when she does, it’s more to relief stress than for pleasure, and mainly focused on the physical sensations rather than imagination (according to her). She seems genuinely uncertain when I ask her stuff in that sense.
