Should I start shaving now?

lol dude im 18 and all im getting is a faint mustache, and just recently i got my first chin hair, im a slow grower and ur a quick one. basically if you shave your mustache and all that, itll grow back, it will def. not stunt its growth. itll grow faster than it did the first time. but shaving it will possibly make it grow in even, since u said its growing in bizarrely, i imagine its pretty un even. lol your mom wont be dissapointed, bt id ask good old dad.
