Is it cheating to masterbate to other girls while in a relationship?

[JtG Da Merc]

It's facebook to be honest ALL guys creep on girls pictures and i know girls will be shocked to hear this but yes guys jack off to hot girls facebook pictures . It's common place now whether it's wrong or not , the answer will be different depending on who you ask . But your looking at the pictures anyway , what difference does it make to look at them and rub your dick while your doing it . Girls should expect this . Boys have been jacking off and thinking about there classmates forever , the only difference now is that instead of imagining them you go to there profile and see them .
I only add girls to look at there pictures , thats it . It's normal nowadays simply google jack off facebook and you'll see tons of results

Is it cheating ? Is watching porn cheating , it's the same thing but with girls you know not strangers so answer that for yourself
