A lot of this comes down to what you, specifically, want and how that fits with what a potential partner wants.
In general, a bottom receives and a top delivers whatever it might be in a specific scene. Like the sweater analogy, one of you wears the sweater while the other provides the sweater to be worn during a specific event or at an agreed upon time/place. Top and bottom are what you /do/.
Similarly, a submissive might wear sweaters because they can't imagine NOT wearing a sweater selected for them, while a Dominant might not be able to turn off their desire to dress their partner in sweaters. Dominant and submissive are what you /are/.
(And that's where it can get confusing, because you can totally be a Dominant who bottoms in a scene, or a submissive who Tops in a scene... It just depends on what you've negotiated in that specific moment)
Which would make negotiation a process of determining what sort of sweaters are available, what materials are out due to allergy or dislike, which styles are the most flattering, I suppose? (I'm LOVING this analogy, btw!)
Anyway... If you want to wear that sweater all the time, because that's who you are, there are people who will be happy to select a sweater with you. And people who will understand that there same sweater won't fit all the time. I'm in a 24/7 D/s relationship, but my relationship certainly doesn't look like the sort of 24/7 you might find in an erotic novel. We both work outside the home, we have kids and all the challenges parenting provides, we have different social interests (I even wear clothes and eat at the table nine times out of ten
)
For us, the "sweater" I wear all the time is that he is the decision maker and I operate within boundaries he assigns. He has responsibilities that I depend on him to complete. When we have private time there are other sweaters he pulls out for me to wear, and I love those sweaters... But they're not the foundation of our relationship. Like any relationship, we talk, we negotiate, we share our hopes and concerns, and we move forward together.
Which is a really long winded way of saying... If there is something you want, there is most likely someone out there who would enjoy giving that to you. Places like the Cage, or your local munch, are great options for starting a conversation with someone and seeing if their desires line up with yours.
