Questions

So I'm a 20 year old guy, and I've seen a lot of videos and infographics that talk about how you should choose your hairstyle and facial hair by your face shape. Using the technique, I'm very confused. I feel like i have a triangle and rectangle face at the same time, which honestly kinda makes choosing this stuff hard. I do like my hairstyle, though, as it is a mix of a quiff and a combover, which I feel suits my face very well. However, when it comes to my facial hair, I'm really confused. Mostly up until January of this year, I had been rocking minimal stubble, and while a lot of infographics say triangle faces should have minimal stubble at most, I felt that my face looked really, really large and I never really liked it. However, after growing it out to about 8-9mm, I really started to love it. My parents don't think so though, as they're always saying i need to cut it off. However, I have never liked being clean shaven, and I don't feel like myself without at least a heavy stubble (5mm) at minimum. I really like the 8mm I have on right now, as I feel it gives me sort of a more mature, edgy look. I've heard that girls my age won't even really give me a chance if I have a beard, but I don't want to have to shave just to possibly get girls.

I'm just curious as to what your opinion is, and I'd love to hear from both guys and girls. Tell me how old you are, and why you chose the option you did.
