It's always interesting how these things work.
Sometimes I meet a sub and never press her in the slightest. Other times, it's a full court press. But even when I am in full go-mode, I offer opportunity after opportunity for her to call a halt.
When I don't press, the relationship rarely goes further. When I do, the chemistry becomes palpable. So even though I'm pushing the boundaries, the results are worth the effort. I haven't been rebuffed for pushing, I guess it's in the approach.
And that said, what is important is that each is pushed to exactly the edge of her personal precipice... and allowed to step over the edge on her own.
