They are awkward and got teased growing up, tbh..
Being a giant is cool when you're a grown man, or even when you reach your late teens, but most of them got teased and shunned in elementary school, which translated to awkwardness in middle school/early HS, tbh..
So, once they get some money and gain confidence by making it to the NBA, they revert to dating/ ing the types of girls that rejected them in their awkward/teased stage in life IMO..
The Disney thot that Drummond was smashing said something about him being shy/awkward IIRC, it's how it is(with rare exceptions like Shaq)..
And in cases like Hakeem's, he was just raised in a ed up society with a ed up religion
