I was in a relationship with a woman there for a while who put a ban on my ability to jack off, but no ban on masturbation or porn for herself. Her logic was that if I were to jack off, I'd lose that desire and sexual energy and the sex between us wouldn't be as good. The difference was that if she pleasured herself, there was no downside to it - she didn't lose that desire and she could cum as many times as she wanted.

I wanted to argue against this logic, but it played out a number of times, in which I wasn't able to perform with her in the way we wanted. Plus, when I did start refraining from it, I *was* better in bed. She just always thought it was funny to tease me about the fact that she could touch herself and watch porn all she wanted with no downside, but I couldn't. Pussy envy indeed.
