Lots of people find excitement wanes in ltrs. Lots of people find their sex life takes a back seat/is sketchy during baby and early childhood years.
100% of them (what percentage do one can only guess) are not buying private intimate/sexusl pics of sex workers, having xan sex with sex workers, and having hand jobs and (now) blow jobs in essentially brothels.
He's an unreasonable, low integrity, cheating, sex worker using, fucked up, degenerate, disloyal, deeply selfish, deceptive, two faced/compartmentalising, disrespectful pos.
He's not relationship material and not family man material.
He's just another wankng, brothel crawling, Internet sex punter; ruled by his dick. No decency or loyalty towards the the person person chose as his life partner. And by extension none to his family.
His views of sex are clearly highly entitled, detached, clinical, exploitative etc. ("This appliance is not functioning, pay for another one"). Not someone you want to be in a relationship with.
There are women on here who've dumped guys like this, they always get new partners, and the relationships last as long as the new partner takes to catch them at it again.
The sex workers who've commented on hete say a punter is a punter for life, its always their last time (even in apparently happy relationships).
Sometimes the poor fuckers believe their lies and blame and stay.
As an aside "coveted blow jobs" seem quote unusual in the sex industry. The std transmission rate is seen as low, punters don't want them, prostitutes are often willing to do "owo" (oral without) for a bot more cash, so I'd doubt that too. But that's by the by.
