I think it actually goes both ways. Autistic people seem either more likely to have, or less likely to mask, certain traits that are culturally considered atypical or "not right" for whatever gender we're assigned. It goes for men and women both. As an autistic woman I often get seen as actually male even though I've got huge breasts, and when I'm seen as a woman I get considered to have "male" traits.
The main difference is that since women are less valued than men, a man having "female" traits is less socially acceptable than a woman having "male" traits. A woman having "male" traits can be seen as "a step up" in some ways. A man having "female" traits, that's one of the worst things a man can be accused of at least in the USA.
(Personally I don't consider myself to have a gender at all, so it is all very confusing to me keeping track of which traits are supposedly male and which are supposedly female.)
