I don't think you are out of your league at all. Different people like different things, just because I like this doesn't mean s/he likes that, and just because I won't do this or that does not make me any less of a submissive (or any more of a submissive) than the next person.
It's just like food, we all like different things to varying degrees, we just need to find the person we click with that likes the same types of things we do. They are out there, it just takes takes time and patience (Side note: why does it have to take time and patience, can't it be two other criteria?) to find them.
If your partner likes you and has no qualms, then don;t worry about what other people have to say, or what they might think.
We are all unique, after all if we weren't life would be pretty damn boring, wouldn't it?
