Is AUTHOR wrong in the post ? POST : I had an healthy realationship when I didn’t feel uncomfortable by the fact that my gf thinks that I shouldn’t masturbate because she feels insecure and replaced by my sense of pleasure.
Note that I don’t masturbate often, only when I feel like it. I feel pretty healthy and I never thought that was something wrong about doing it. It never replaced my sexual activity whatsoever or my feelings for her. We openly talked about it  in casual sex conversation and she said she would break up with me if I did it again, for the reasons mentioned above.

For a while I didn’t thought about it too much, but we were moving together..if she catches me doing it, she would break up just for that?
Well this made uncomfortable just thibking about it so I brought it up again as conversation subject. Well she broke with me, because I said I cannot guarantee nor do I want to stop doing it. So am i wrong for doing it? Doesn’t everyone does it?
