Hi. It may be simple flirting and he may never meet them. It might seem weird but you could ask him if you can join him sometime when he chat with those women. It might simply be the thrill of the hunt, so you may be able to give him a bit of that by not giving it to easy to him so he does not need to look for it elsewhere .
You may also get him into an activity that would fill basic men needs, like animal hunting or playing a sports weekly with other men (preferably a large team sport). It would divert away some this.
