I laughed at your comment about "few (if any) friends of the same gender"
I have noticed the same problem. Interesting to hear someone else say that, too. I always thought it was a "native male" thing... women could make native women friends that were only friends. Any native men "friends" were roughly always trying to be slightly more than friends. Men could make native women friends and truly only be friends. Men didn't make friends with many native men, at least beyond superficial relationships...
