I have a really big nose that makes me look kinda like a witch
And I'm 23
Can I get a boyfriend or should I give up on that?
I have a big nose too, and my boyfriend (unprovoked and unknowing that I dislike my nose), has complemented it and said it's a feature of mine he really likes.
There are guys out there who will not notice, mind, or care, and there are even guys out there who will like it, believe it or not.
It means don't worry. It won't be an issue. You're young, and if the one thing you are worried about is your nose, then you are perfectly fine, don't give up before you've even started.
I'm a guy and I can safely say I and the vast majority of men would not give a fuck about a big nose. Jaw structure, cheeks and eye shape/distance are way more important than noses.
