I bet you're considering shaving it off for two reasons,
1) It looks like shit, it isn't as fierce as your old mans and you feel de-maned by that.
2) You don't think you'll get any with a stache,
Well, staches are for men who say fuck conformity I'm going with a niche market...
FACT- People are attracted to those who like like their parents (or whomever you were around as a child)
FACT- Lots of dad's have creepy ass staches, thus that niche market exists, plus you're a novelty. How many males in the under 25 category rock moustaches and arent creepy as fuck (assuming you aren't creepy as fuck)? Very few, and that gives you a chance with all those girls who are willing to experiment.
Sorry, i can't help you out with your stache looking like shit, but whenever you look in the mirror and wonder "wouldn't I look ten times better without this stupid fucking thing hanging around on your upper lip?" just think of how upset all your internet friends would be (and that niche market of girls who for whatever reason want to hook up with a dude who has a moustache).
