I have a question for fans of iStripper: do you mostly fantasize about submitting to the girls on your screen?
Interesting question. Answer from me is "no".
Usually I'm barely engaged with the show emotionally and remain fairly detached intellectually. I'm just buying eye candy and I don't fantasise one way or the other. A BDSM theme is just a variation in costume. The beauty of the performance, along with the spice of nudity, is what attracts me. I suspect tht I'm not alone in this.
For me, iStripper isn't really a medium that distinguishes between femdom and femsub, other than at a very trivial level. Other products do that and it's important, as you say, that they do it properly to sustain the fantasy. It would take a performer with decent acting skills to play either dom or sub consistently during a striptease and I don't think the directors have that available to them. So I don't think that we can get Totem to improve the artistic range, unless they substantially change the proposition (actresses, choreography, less than 3 shows per day, etc.).
So I'm ok with iStripper as it is - or would be if there were more e-series cards, but that's a different matter.
