Welcome to the forums mate.
I'm 26, started shaving bald when I was 25, and let me tell you mate, you're never too young to start shaving

If you are already clippering down to a 000 then the razor is going to look no different, but the feeling is awesome! The other option, is that you can razor cut down, but only shave every few days, that way only on teh first day you'll be smooth, and after day 2-3 you'll look like you have a very close buzz. That's how often I normally shave my head, and I think it works well for me, maybe it will for you too.
The feeling of the being completely sly though is the biggest draw card of me, it feels so amazing! Then there is the shine... I get heaps of compliments on my shiny head these days, it is such a boost to the confidence

To address your 2 reasons, kudos to you for wanting to be perceived as balding, there are very few out there that feel that way... I'd much rather be perceived as being in control of the situation myself

But on the other point, I think you are being to critical on yourself! I'm yet to see a guy any age, that doesn't loo good completely bald. Without a pic it's pretty hard to tell where you are coming from, but I'm pretty sure you'll kill the sly look!
I think the 30 day rule would be a good thing for you to try, even if you don't shave every day, but every other day or something like that, it will give you and the people around you time to adjust to the new you, as well as give you time to perfect your technique and routine! Be warned though, you wont be prepared for the compliments and head rubs!
If you take your time to read through the introductions, 30 day and to be or not to be sections you'll find many stories like yours, and it might help you to take the plunge.
Either way, just because you don't shave your head with a razor, doesn't mean you can't be a part of this great community, so just kick back and join in the conversations, and when the time is right for you, we'll cheer you on as you take the plunge.
