I just read this entire thread...
After much advice and warning and some bluntness bordering on rudeness, we start coming to the crux of the matter.
Miket's wife joins in the conversation. For some reason, she has chosen to call herself a Slut. A fun Slut. What is that supposed to mean? Define your view on slutdom. Will you fuck anyone? Or do you just really enjoy down and dirty intense kinky sex? You enjoy sex with Mike. You enjoyed sex with your former gf. You're fantasising about enjoying sex with other men now as well. So, you feel slutty?
OK. That's some questions about your nature, FunSlut. Welcome to the board.
Miket, we find out, is or was (probably still is) jealous of your former boyfriends. Only a couple? Only 2 men you had sexual relationships with before hooking "good provider" Miket? And he is so jealous, of people you met before you knew he existed, seeing a mere picture of one of them sent him into a tailspin for days? That smacks of low self esteem to me. It sounds very very sad.
Is he so out of touch with our contemporary move away from patriarchy? Is he into Trump's idea to "Make America Great Again" by taking away women's autonomy, by removing their health care, education and job, so they can be kept dependent, barefoot and pregnant in the kitchen? (And of course, you're so tired from multiple pregnancies and chasing kids, and you are resentful of his independence, you have little to no desire or energy for sex, and so he gets to have and fuck and wine and dine, a glamorous single gf).
I assume you two are young. Late 20s, early 30s? Why the outdated ideas? Look around, the patriarchy is falling. Women have been working for their rights since the late 19th century. This is 2017. Granted the patriarchy has been in place since about 2000 BCE, but it took about 1500 years after that to squash women's power (using violence and saying it was god's will) and own them, body and soul. To control their sexuality and their fertility and economic independence.
But now, now that you (plural) are dipping your toes in polyamory, you start to realise it's not about sexy MFM threesomes with 2 hot bi babes and one straight guy getting double pussy. The new contemporary polyamory is a woman driven movement. It couldn't exist without feminism. It's about women, as well as men, being able to have lovers of any gender they choose. It's about women's autonomy. We are no longer possessions! We are not owned! We are not slaves!
These are the underlying concepts you must ponder as you work to overcome the One Penis Policy. Broad overarching concepts.
On to specifics: Miket thinks your vagina was tainted by having had other penises in it before you knew he existed. He would have preferred you virgin. He has grudgingly accepted you were a "slut" before you met and married him, having actually had lovers (specifically male lovers with PENISES).
Now, the double standard gets worse. Not only does he resent your former sexual relationships, he himself was actually MARRIED to another woman. Having those shitty patriarchal ideas, it's no wonder to me she cheated on him and divorced him.
Is Miket afraid your hypothetical future male lover will have a bigger cock than he does? A better job that brings in more cash? Better home, better car(s), more money to wine and dine you in the best restaurants and bed you in the finest hotel? Take you on expensive vacations? Buy you expensive gifts?
He isn't "paying for you to fuck other men." You have the same job. Because of the patriachy, you earn less.

But you're about as equal as a woman can currently be in our fucked up society. Claim your rights as a free independent person. They are there for the taking. Why did you choose a man who wants to hold you down and limit you like Miket does?
