I think that pitting sex against spirituality is a mistake. To love someone and want to please them sexually, and to be pleased by them sexually, is to see and relate to the divine within ourselves and each other. That partner offering themselves to us is a gift from God, and the sex is a physical reflection of that gift. And to honor that gift we want to offer them ourselves in return.
You say you want a spiritual partner, but are you spiritually ready for that? And what's with all the cats? Pets are just pets. They're easier than people, but to choose them over people doesn't sound very spiritual, to me.
Sounds like you want a trouble free relationship more than a spiritual one. But relationships are not trouble free. They make us have to adapt, and change, to work to meet the other person half way. It's part of the deal. Especially in the beginning.
I respect not wanting the drama, and compromise at this stage in your life. But that probably does mean you'll be living alone.
