Wade, I think I might find that kind of scenario kind of exciting, though not (for me of course) ideal! Thank you for sharing your experiences.
I am in a long-standing relationship with the woman I love and will always love, but when we dated she gave me the impression she was ticklish, but I found out after we married that she wasn't at all.
For years I have tried and tried to find a spot(s) on her body and nothing. She knows that I love to tickle and she is sorry she can't accommodate. Once she found out that I needed to tickle, she at least let me tickle her all over, even though she is not ticklish.
I feel that something is missing for me, especially as I get older, but nothing is going to change. To answer your question, if you love her and want a relationship with her and she lets you play with her, like in my case, it is better than nothing. She seems to understand the situation for you.
Let us know how it is going.

Yeah, it's ideal for me, because I'm not really a tickler at all, and for me getting tormented by someone I can't retaliate against in kind just enhances the psychological power dynamic.
Someone just asked me what is it I love about being tickled. What you just wrote is also what I love. I have only experienced feeling truly helpless once but it was an amazing experience.
As I said good relationships are much harder to come by then one expects in life. I'll also say that being sexually satisfied is an important aspect of life also. The question you face is if you can be satisfied sexually without tickling, through all the other possible options out there that are open with your partner or not. If you cannot see a way you'll be happy in this relationship without tickling being a part of it then you should move on. But if otherwise, then enjoy what you have found, and see if other things are more valuable to you then tickling, and if you can indeed find pleasure in other ways too.
Nothing is ever writ in stone. And evolution is the natural path for all interactions. Those that stagnate also tend to die.
