Wife swapping is just a game
Let me begin by saying that, that was a very long question you posted. In this age of 2 minute noodles, most of us may not have the time to read such a long post. I posted it (after shortening it by almost a page), as the English was flawless and you have given us detailed background to frame an answer.
You are living in an Utopia or hope to live in one in the future. Yours is a recipe for disaster. Marriage is about Family and you talk about it as one big orgy. We all have high sex desires, but we have learnt to temper it with caution for the sake of family. All your Education and all your earnings will come to nought if your Family life is flawed. Peace of mind is what we all aim for, but your planning for the future with your course of action, is asking for the keg of tension to ignite. What happens when you come back from this posting? Just because it happens in the West and no one is bothered, same will not be the case in your home country.
You keep on harping that you have no emotion when you visit Escorts. In this case you are paying them. Swapping is another kettle of fish. Swapping requires a level of comfort with another couple and some level of familiarity. Human emotions can never be predicted or guaranteed. There are many cases where either partner has fallen in love with the other, leading to a messy divorce. I am just stating facts.
You have also stated that your fiancée is quite broadminded and enjoys sex. I say you know nothing about her. Just watching porn does not make one broadminded and willing to risk their life. For starters, you do not know whether she has had sex with others. I am bringing up this topic so that I can later explain about swapping and what it entails. The fact that she has refused oral sex and intercourse before marriage is a clear indication of her thoughts and mentality. You are planning to ask for her permission to initiate swapping. It can never happen. It takes years of being married, before you can speak of the topic with her.
Your asking us for advice about initiating swapping is a futile exercise. The most important ingredient in this is the participation of your wife and it could take years before you are able to break her resistance. Your concept of “sex toys” is infantile to say the least. You talk of your Escorts as toys and in the same breath say that you will get a couple as a “sex toy” for your wife. Sex toy, like dildos and vibrators do not make “demands” and perform what they are meant to do. When you replace these with people, the equation is different. If you think that you will get swapping partners on demand in India, you could be sadly mistaken. Imagine getting 4 people to agree on this.
The only point that I would like to stress is your question 3. Since this is the question that matters. If you say that you love your fiancée and will continue loving her as your wife, then you need to make the effort. Your past does not matter. Honestly, have you told her about having sex with Escorts? I would love to hear her reply. In that you will have your answer to your grandiose plans for Diwali.
Do let me know if what I have predicted is true. I am willing to wait till the next Diwali.
