my boyfriend doesnt want to socialize with my friends

I am torn by my boyfriend’s behavior. We’ve been together for 6 ½ years and I care about him deeply. I am in my late 30th and he is 9 years older. I do think he is a good-hearted man who means well, albeit abit stubborn. Here is the situation:

I am an immigrant (my whole family lives oversees) and I used to work a lot of hours when we first got back together. I switched my career a couple of years ago and that is when I started realizing I want to expend/improve my social circle. This is where our arguments have started. He is extremely extroverted (when traveling or out and about he has the need to talk to every single person. Basically his whole career is based on calling strangers and getting them to catch/connect with him at some level.) Sometimes I think his interactions are repetitious (like a salesman), but I also see he has been able to developed true friendships where his friends rely on him for personal/career advice and it’s also pretty obvious they would be there for him if needed.

However, he doesn’t like to socialize with my friends. For the most part I don’t mind socializing alone (he doesn’t prevent me to at all), but from time to time I do like him to come along (especially if it’s a couples things). We have fought over this and we have established some compromises. He promised to attend one thing a month if I really want him to (which ends up being more like few times a year, so I don’t ask him to participate often). I do think this has helped abit - he is starting to understand how important having a social circle is to me. He also puts up less resistance, but still this whole process is not smooth and it remains a battle between us.

For example, the first time in the 6 years we’ve been together I hosted a little sport-event-watching brunch party at our place. When I first set it up, it became a whole issue him being upset that he had to be part of it. After a fight, he apologized and agreed to participate. And indeed he did stay for the whole game, but left right after the game for a bike-ride when the first people started leaving. I thought it was rude and we got into a fight about it, but reached a conclusion that he indeed try his best and people started leaving already anyway.

He can also be very intense with people. He would be the guy asking an Asian friend whom he just met whether she would date white guys, etc. Sometimes he just say things that I find inappropriate. Again his contra-argument is that he ‘would bet his money on him’ how to interact with people given he has made a very successful career based on building personal rapport with people (and that is true.. he has created long lasting business relationships where his clients also end up inviting him to weddings, etc.). I know some of my friends find him a bit odd…

So the dilemma is: am I being too demanding and unfair? He resists saying I have standards no one can live up to and am too uptight. My argument is that from time to time he should compromise and socialize with my friends without creating friction. I feel like we both are trying to find a middle-ground and do things that we don’t necessarily would otherwise to save the relationship. I just want to understand whether I should back-off and let just socialize on my own (apart from very formal events, such as weddings, work parties, etc). I am just very tired of fighting with him about this issue.
