A different take...
I actually come to the hobby when I want something more vanilla. Just to suck, fuck and play, and walk away.
I wouldn't pay to have my fetishes fulfilled as that takes away from the experience of fulfilling my fetishes...if that makes any sense.
Being in the BDSM lifestyle, I want and need to have a submissive submit and take to the fetishes willing and openly...not responding to me and them because she is being paid for it. Also, I am extremely passionate about long term extreme and edge play role playing....I simply couldn't afford to pay for that fetish....
And limits for me are scat and blood...and another taboo activity mentioned that I don't want to get in trouble for mentioning....so my freak flag may not be flying too high....
