Pluses and minuses.
+being with someone similar to you is easier - less need for flexibility.
-different aspies are different, and it can be harder to adapt to those differences (Aspie-NT==square+round wheel, Aspie-Aspie==2 square wheels...lots of sparks and fragments everywhere.)
-inflexible communication styles and limited executive function can be a bad combination.
Penelope Trunk's parents may be an Aspie-Aspie couple - she has a blog. Problem is that her parent (while well-off and successful) had _a lot_ of police calls.
My in-laws would have been the same, except for residing in a country where jokes such as:
Q: What do the police say to a woman with a broken arm?
A: Go home to your husband.
are actually fairly representative of normal behavior.
My own marriage is challenging, partially because of my wife's resulting upbringing and accompanying behavior, but more so because:
(a) flexibility can be hard, executive dysfunction is a big problem
(b) there's less margin for either of us to exhaust ourselves - as an NT spouse can often cover for an Aspie who needs time alone instead of, eg, doing the dishes, and I believe that an NT would be better at dealing with my wife's anxiety issues.
(c) Having two people who often miss the other person's point of view is challenging.
That said, there's pluses, as an NT would probably have significant issues dealing with my wife's tendency towards extreme plain-speaking and an NT woman would probably take issue with a lack of charming romantic gestures on my part. And, we do have a strong bond.
I'd actually suggest just selecting for women with compatible interests and looking more for, eg, personal compatibility in terms of interests than looks. In practice, women are so under-diagnosed (IMO) that Aspie dating sites are probably not too effective for men. F'r instance, a friend with boardgames as a special interest found a girlfriend who also does nothing but boardgames (and larps..but he's kinda okay with that). Another completely NT musician, though fairly co-dependent, woman is fairly happily married to an Aspie with a strong interest in music.
