Am married to a bald guy, he only has hair on the sides and am ok with it. We occasionally play around with his head and my kids tell him he has a playing ground. He has no problem with it too.
My hair is currently very wild and curly when it's longer, and thick and straight when it's short. I hope that it will stay that way forever lol.
But yeah, no need be ashamed. It's a natural process.
