Does it mean I am ugly if a guy has never asked for my number before?

So I am a 23 year old girl and I have never really had a guy ask for my number before out in public. I am 5’4 and 120 lbs. I never really thought I was ugly but I hear it happening to other women so it makes me question my attractiveness. I have only been approached by men to tell me I am beautiful but never once has a guy asked for my number. Do you think this means I am ugly?
