The way you ask the question, it appears that you’re looking for a yes or no answer, but I’m afraid it’s more complicated than that. The danger from “too much” masturbation is that a woman can get so used to getting an orgasm in a certain way that she has difficulty in other ways. Now I can’t say what “too much” is in relation to this risk because it’s going to be different for each individual. One girl could masturbate four times a day (not that I recommend that) and not find any problems when she’s with a man and another could masturbate once a week and develop the problem of being too set in her ways. So I would say the answer to your question, in general terms, is moderation and variety. Try not to masturbate more than once a day, if for nor no other reason that there are better things that you could be doing with your time. And try not to masturbate the exact same way each time you do, no matter how often. Insert as much variety in the technique you use so that you don’t get dependent on having orgasms one way only.
