Well, I would vote both that I have a problem and that I don't for my fetishes and "kinks" becoming more extreme. There are certain ones that I am alright with, but others that I find myself getting upset about because I feel as if it's sick of me to want those things.
Urination is one of them. I had a talk with a friend about it a long time ago, and I said to them, "That is absolutely revolting!" Now, I am willing to not only feel it but also drink it. Go figure. HAHA! That one I'm alright with, though.
I have a fetish for blood that I do not talk about because it has made my partner nervous. That's one of the few that I'm not alright with, because when that fetish is indulged, it becomes heightened and more extreme.
No, I do not feel that I need more taboo activities to get me off. Sometimes, I just go back to the regular every day crop or cane, and sometimes even just my hand, to smack my partner's tush with. Nothing interesting. And I am just as pleased as if we had introduced something more "disgusting" into our play.
