In a close relationship. no need to masturbate alone. I am weird?

I'm happily engaged 3+ years, we live together since 2014, our friends and families are part of our lives as couple (we didn't come out in workplaces as we prefer to wait until we'll get "married", now in Italy it's possible to have something like a marriage for homosexual people).So, why I'm writing this? Because, as the title says, I don't find the necessity or the desire to masturbate myself. Since the beginning of our relationship, we have chosen to be in a closed relationship, so it's not possible for one of us to have sex with someone else.Although we know some gay couples, it seems to us that a large fraction of them are in an open relationship, whether they discuss this publicly or prefer to keep secret this part of their life.In fact, one year ago, we were in a nudist beach and one of our acquaintances was very surpised when we told him that we don't have sexual affaires with others. In fact, he declared that all the couples he knows were in the open relationship scenario.But, further from this, I am in a even more exclusive relationship with him, as I do not masturbate myself. In fact, I think I wanked a couple of times at the beginning of our relationship, but suddendly I realized that, as I was thinking to him to cum, I'd rather prefer to cum with him.He is almost in the same mood, I think that he almost never jerked off himself in these years, although some times he did so.We have a very normal, although passionate and fulfilling sexual life together, in fact we started as a top/bottom and now we are both versatile, and we both enjoy this.Of course, this approach of not cum alone (in fact, some times I masturbate me in front of himself, because as an example he was tired, a bit ill or whatever and I need to cum to reduce the tension) has some drawbacks. Especially when you cannot have some for some days and weeks (conflicting schedules, minor health issues, not accordance on the same sexual mood) it could be a bit difficult to wait for your time, and in fact I had two wet dreams in the last year or so (I'm 40 yo, so it's a bit unusual at this age)So, people of reddit, feel free to ask anything but I'd like if you share your thoughts with me: are we strange? should we start some kind of "autonomous" sexual life? Are we in an heaven and should stop worrying? Will this exclusivity last forever or it will change?
