Nope. That's how it was supposed to work. Once you experience the pleasure it overloads the synapses rendering them useless. I tailored it specifically to you, after all with all these toys of yours I stole I have ample dna supply.
No choice then, I have poisoned you in a way you wouldn't suspect or resist. No more sexual pleasure for you. The antidote exists in only one place, a place I won't ever let you go.
