Fascinating the willingness to throw everything aside and "Angry Mob". Relationships need working, in fact our minds need working.
As a man, one that a years ago while in a relationship would once in a while browse local sex workers (for years) but never ever took it the next step. Then after breaking up a long, loving, childless, and finally bitter trapped relationship and having a messy rebound or three and strung out out all night, did finally act upon visiting a sex worker from Adultwork. All was safe, no damage done they seemed independent and in control of their life and quite happy about it all.
BUT how much did i regret it. How low had I become.
At that point decided this was not the person who i wanted to be and to seek some therapy. After a while of speaking to other men, and a friend who is a sex worker it is doesn't seem uncommon to have visited a Sex worker at all sadly, 50/50 on people i have spoken to. It is the oldest profession (don't want to normalise it, just there seems to be 9099 of them in London on Adultwork. London only has 205 McDonalds in comparison). Art, TV, Literature all toys with the exoticness of it all. Let alone the utter sexualisation of everything, everywhere.
Looking back over relationships, thinking it is common tend to build up and harbour fantasies, porn, literotica, etc. The best relationships are were sexuality is utterly shared. Where fantasies are shared without feeling like they need to be pushed down or kept away. Where you grow as sexual beings together. If this is being kept down, unfortunately like a nasty weed it finds a way.
It is in counter intuitive to your feelings I imagine, but to get the truth out of someone entirely, you need to turn into the skid. If you go in blasting accusations, you are going to get denial and subterfuge of any of this stuff in the future too. Go in all playful and relaxed, way more likely to get the truth, like a friend would, ironically like the Sex Worker would.
Ultimately Sex with a sex worker is an rush, an act, a physical act for an hour or two. The best sex is mutual exploration for an evening, a day, a weekend. Forever. And the best bit the partner curls up asleep in your arms afterwards.
