'More Pretty' I am guessing, means the same as 'Very Pretty'. There is of course considerable subjectivity involved, but I catagorize 'Very Pretty' as someone just about everyone would consider pretty. This usually means all the main features are very positive, such as facial features, body type, hair, etc.
When women are young, very many meet this criteria. But fewer maintain it long term.
In a general sense likes attracts like. So while you may have more difficulty hitting it off with a typical NT lady, you are fortunate in the sense that there is no shortage of attractive and beautiful women more similar to you (ie, On the spectrum).
But to be attractive to others you have to work at being as successful as you can within your limitations. That means what you can do, who you are as a person as well as maintaining your physical appearence (Personal care, diet, exercise, etc) Women in general are not so focused on looks as men. They consider more the whole person. Men I think are wired more to be attracted to looks. Something left over from our days living in trees I expect.
