Ok, I'll bite. How does one get banned after a single (only mildly grammatically incorrect) post on masturbation in September?
The reasons I've gotten from others on why not to masturbate have varied depending on my age, but it was usually some variation of "it takes away from your relationship with [God, your family, your partner, etc.]
Only one person ever tried the non-guilt-tripping route by telling me to google Peyronie's disease. Smart man.
To be fair, "if" your partner is getting completely fulfilled, then masturbation (for either partner) shouldn't be an issue. Honestly, I feel like most negativity about masturbation is driven towards *what* the person in question is masturbating to and whether it's unrealistic or degrading, than the masturbation itself.
(edit: although, after some thought, I guess it's fair to reply that masturbation in a relationship is often interpreted by the other partner as a rejection or statement of sexual inability- although those things, by definition, would mean that a partner is NOT getting completely fulfilled.)
But it's up to communication because, like a lot of other sex in marriage topics, that's a big "if". And I'd find all the things @TJW
listed above understandable to bring up.
