I've very recently separated from a serial cheat and when I described his behaviour to a friend she suggested perhaps he was a sex addict (not in his defence, she thinks he's deplorable)
He had at least two affairs that I know about and conceived a baby with one of them despite me being heavily pregnant at the time. He watched alot of porn and got off on sending naked pictures of himself and videos of him masturbating. I also discovered that he also cheated on his previous ex multiple times but I didn't know about that when we met unfortunately.
He would pester me for sex on a daily basis regardless of the fact he was getting it elsewhere and took no precautions so he was putting everybody at risk.
It's also worth noting that he wasn't fussy about where he got it, so long as they were interested in having sex with him.
The last woman he cheated on me with looked old enough to be his mother, was unkempt and a generally nasty piece of work. I mention that only to highlight the fact he wasn't necessarily seeking out somebody 'better' just anybody who would have him.
Not a day went by where he wasn't fantasizing about sex or seeking it be it from me or an outside source.
Do you think sex addiction is a thing in general or a red herring to explain away disgusting behaviour?
