Alright, i do get what you are saying here....
so you believe that the visualisation of something that doesn't resembled one's partner is more damaging than perhaps the manisfestations of a woman's mind (which she uses to conjur up images while using her own sexual aids). The thing is that her psyche can't be visualised by others. Also we can't tell whether the images being seen are a deep routed fantasy based on either one made up or past individual, which could be more 'damaging' relationship wise than an assorted array or ladies normally displayed in pornography.
Here's my point.
If a man and a woman were to display their sexual aids infront of you, a lady with numerous vibrators and other implements would come out smelling of roses in comparison to a man who has this bum unit with two vibrating holes. (man it's hard to post this with a straight face).
on a fair level, it's certainly not even. Even simply using magazines as a supplement for a man instead of the bum, a bag of magazine still makes him come across as worse.
aids for women liberates. Aids for men seem to taint.
you see where i'm coming from with this?
