Everyone has their preferences, but it's probably safe to say it'll open more doors for you, if you decide to lose some weight (I'm rooting for ya :D) . For me, it'd be hard to me to get with a girl if she was overweight. I know it makes me a bit shallow, but I can't help it.
I feel like, it's just unfair to me, because my body is something I'm consciously aware of; and I've worked hard to get where I am. It shows a lot of self respect in my eyes.
As for your height, I don't think that's an issue. It's not exactly something you can change anyway, so don't stress on that too much.
I'm 5ft3 and chubby, I seem to get plenty of attention from guys. I'm just extremely picky when it comes to men. Don't worry some guys like short women.
Honestly you are not chubby at all, I am 5ft and used to be 10st3. I got told to lose weight and that I was chubby and I lost three stone in a matter of months and developed an eating disorder which I would not want to wish on anyone else. I was eating less than 600 calories; and I eat 1200 now. You are fine the way you are! Honestly I wish I never lost the weight as my breasts have sagged and I'm only 16 years old
