Just for the sake of asking, are you a natural blonde? Does your facial hair grow in in a light colour? I really couldn't tell from your current pic up there.
But if that's the case, I wouldn't, as a lightly-coloured beard always looks like shit. But if otherwise, go for it. I mean, it's not like you're signing yourself to a second mortgage or anything - it's not a life-altering decision. Don't like it? Shave it! =]
Myself, I've never eaten meat, so I don't have those steroids they pump into the livestock pumping through my body, so at the humble age of 20, my beard is still choppy and looks like ass. I like it though.
