Socially awkward means you don't know how to interact with others in a public setting, so yes, many men ARE socially awkward because they have spent all their time on screens and playing video games growing up instead of out socializing with others.
It's so bad these days kids will sit around with each other and instead of talking they will all have their heads buried in their phones and will be
texting back and forth when they are literally 5 feet away from each other and go hours without saying a single word. WTF is that??
Is it any surprise people are socially awkward? It's like anything else, if you don't practice it very often or do not do much of it, you don't develop the skills and nuances needed to do well at it.
