Welcome to the board - for me the biggest challenge in growing out my beard was more the mental adjustment to seeing and feeling the hair on my face. I really liked the look of the guy in the mirror's beard, but it was really hard for me to see that he was me.

I think this is a more common problem with guys who have very thick and quick growth (like you). You've stopped shaving and in no time flat, you've already got a very mature looking beard.

It looks great! Keep it. It would be an absolute shame to let those genes go to waste. Not to mention that it must have been a royal pain to keep your face smooth.
