I made it clear that I would not enter a relationship with a man who uses porn, nor with a man who thinks it is acceptable to use porn.
Of course there are men who don't use porn. I imagine most men (and women) have looked at it at some point, probably in adolescence, but that doesn't mean they continue to.
Misogyny and sexism are the main issue for me. Objectifying women, the myth of men having higher "needs" or sex drives, the male gaze...all horrifying components of a wider context of abuse, oppression and widespread suffering. And that's aside from the potential abuses and exploitation in the porn industry.
I might, in theory, consider mutual pornwatching if enticing enough, proven ethical, feminist porn were available, if such can be said to be possible.
However, on a personal I'd find it upsetting if my partner was looking at other women and I'd think something wrong with our relationship if I found myself fancying other men. I know others feel differently and that's fine, but it's not for me.
Fortunately not all men are socially and politically undereducated misogynist wankers.
My Guardian Soulmates profile, by the way, simply stated, "only feminists need apply." I decided that as a single mum I didn't have time to waste discussing non-negotiables. I was surprised I got quite a few nice responses! 😂.
