I see two big problems in your profile. First is that it reads really negative. You spend as much time saying what you don't want as with describing what you do want. That's really kind of a turn-off for a lot of folks, even if they fit what you're looking for, so I'd look at eliminating anything "don't want". Leave that stuff implied.
Also, your profile is extremely tentative. It reads like MAYBE she MIGHT consider thinking about playing with another guy. Honestly, I've run into this before, and for me at least, it's a red line that I don't cross. If a lady isn't sure that I'm the guy she wants to play with, that's legit, and I don't have a problem with that. But if she isn't sure if she's willing to play AT ALL, that scares the beejeepers out of me. I'm rather a stickler for having consent be VERY obvious.
Now, that doesn't mean that you should do something you aren't willing to do. Just be very firm and honest about what your limits are. Banish "maybe" from your swinging vocabulary, at least until you're a lot more comfortable with your place in this life. And be realistic about what this means in terms of who is willing to play by your rules. The more specific the rules, the smaller the pool of possible playmates that will be willing to consider meeting you. The flip side of that is that when you DO make a connection, it's more likely to be enjoyable.
