<human>: Can you condense the text into a few key points?

I'm aware it's not uncommon for women to have trouble achieving orgasm through penetrative sex. I've only had one partner before and luckily for both of us, it wasn't the case. But now I'm dating a new woman and she doesn't seem to find it pleasurable.

I mean, not only she won't orgasm, she seems to actually feel "meh" about it.

Her own explanation is that she still doesn't know her body very well to know how to enjoy it. Since my previous partner was exactly in the opposite situation (fully in control of her own pleasure) I never went through a phase in which we both discovered together what kind of moves she enjoyed; I was just explicitly shown... For many, many years... So I basically became a specialist in this particular person.

Although that was super cool, now I have no idea how to proceed with this new girl. The biggest problem is that she also has no idea. Not surprisingly, what worked with my previous partner, has no effect on her.

I do not base my pleasure in penetration and neither does she, of course, but I can clearly sense that she's getting frustrated, even though she has enough orgasms through other means when we're together.

I know that the best way of finding out is just spending time together and exploring, which we are both willing to do, but I was wondering if anyone here went from not enjoying penetrative sex at all, to actually like it, and is willing to share her/his experience with me so I get some external ideas.
<bot>: Partner is frustrated cause she doesn't enjoy penetrative sex. How can I help to make it better for both of us?
