You are not doing anyone any favours, you are charging for a service, that makes it "not a hobby" I am afraid.
I would rather jerk off than pander to your idiosyncracies, thanks anyway. Now go and live your little life your way and carry on with your fantasy existence
Oh, and btw, if you dont want people to call you more than once or twice within a half hour then change your stupid voice mail message ("I won't call you back ha, ha, so call back in a few minutes")
