Give her this mug as a gift and she should get the hint.. then you won't have any more girlfriend problems, since she will most likely leave you
http://en.m.wikipedia.org/wiki/Threading_(epilation) I don't know how much it costs there. I pay like 10 dollars for my eyebrows, I think whole face (including eyebrows) is around 30 dollars. My sister lives in Switzerland, and it's waaay cheaper there, so I have no idea just how much would it cost somewhere else. It's a hair removal method from India. It just makes your eyebrows so defined and neat. Mine are somewhat thick but they're shaped really nice. Would not go back to tweezers. It does hurt a bit, but it's totally worth it. Tweezers pain is much worse, and this is done pretty fast, so yeah. Using tweezers for mustache? Ouch. Sounds like a bad idea.
I know a beautiful Russian woman... very hot body, a very nice face ( shit for brains tho) and a mustache. she's blonde so you cant see much when she's lookin at you( thats why she didn't trim it), but from sideways it looks quite big.
I once hooked up with a girl that had a mustache. It was super blonde, so I didn't know until I could feel it while we were making out. :/
Depending on the colour of the hair and the lighting in her bathroom, she may not even be seeing her stache. I wax, tweeze and bleach. After turning thirty, my facial hair started to slowly go out of control. At Fourty, it's so crazy I'm starting to go back to birthcontrol (for pmdd) but the hormones are starting to lessen the hair growth. Genetics are a bitch.
Yikes!!! lol Seriously though you need to tell her. Yes do it gently and try to pick a good moment (when it's just you and her). Breaking the ice with this kind of a thing is a little touchy and hopefully she doesn't fly off the handle for it. My wife and I have an agreement on that and she actually gets pissed if I don't tell her stuff like that. She doesn't have a mustache per say but she has one little mole above her lip which does grow a couple darker hairs and soon as I see them or feel them if I kiss her I tell her it's time to pluck. Also if we're out eating or something and get something stuck in our teeth, we always discreetly tell each other. It becomes comical at times but hey, being able to laugh at yourself or each other makes life so much more fun too
Dad always said to never date a girl who can grow a better moustache than you can. I am just kidding but I like that line.
My dad always said never date a man with a thick hairy back, he's not all human and you won't go swimming with him ever.
