For me no it doesn't...

Well to a degree - if your unhealthy and not looking after your self hygienically Im a snob and will look the other way - but thats got nothing to do with size more the way you present your self.
I used to be like that too until I had three under 15 months! Getting out of the house was and still a nightmare and there was many a day when I copped a look of myself in a whooshing and thought "oh my god I look like a fat slob"!
