This will probably be repetition of what the other guys said, but I want to add my 45 cents.
I buzzed my head for about 4-5 years before shaving it bald. It was good preparation. There was little fuss between buzzed #1 or no guard to shaved bald. Some did not even notice.
You're young enough, you don't need to shave bald, but I'll tell you, if feels fantastic. It's an acceptable hairstyle for men these days. Lots of bald guys in my community, some by choice and some by nature.
Your current haircut look excellent. There's not 'issue' with the shave of your skull. You look handsome. Nothing to be embarrassed about. Keep up the buzz for now, and when you are ready, go ahead and shave your head.
Once you get the itch to shave your head, it won't go away until you do it. Hope you'll give it a try some day.
