I think we all know (or are discovering) that the nature of fetishes is progressive. This means that with time, we get desensitized to certain acts that used to give us that tingly feeling, so we have to do something a little more extreme, then a bit more, and so on.
I don't know if I'm the only one that worries about taking things too far, but I definitely have this fear that one day I'll be having to parade around in a dress and a diaper struggling to hold in five suppositories in downtown Chicago to get that tingly feeling. I know I'm something of a sex addict, so that's a real fear for me. I don't want my fetish to get old, but I don't want to have to do such extreme things to keep it new.
I wonder if that's what causes the 'binge and purge' thing for some people? Maybe fear of desensitization leads to a self-imposed temporary deprivation that makes the act of merely putting on a diaper exciting?
So, two questions in one: do you fear going too far at all? If so, what acts can you envision that would be crossing the line for you?
