Here are some practical things to consider.
Note that I'm not a believer in "Just be yourself" and similar input. I like the positivity, but I'm a believer in doing some planning and preparation for things that matter.
I'm making an assumption here too, which is that you have the usual "ASD-normal" modest deficit in social skills like conversation. If I've "over-explained" anything, just ignore it. I'll never know (and wouldn't mind) if you decide to do exactly the opposite of my suggestions
So:
A woman considering a relationship looks for different things than a man does (not a popular opinion in the 2020's, but there's a price for ignoring the facts).
For example looks are relevant, but
grooming demonstrates something else - consideration for the other person. Similarly the traditional small gifts (no longer common as far as I know) demonstrate willingness to share resources (this has to be done indirectly now, but the principle should be kept in mind).
Appearance matters. First impressions matter.
That doesn't mean buying all new clothes, but:
* Choose a style from what's in your closet, and present yourself in a way that
demonstrates you've put some effort into it.
* Random, scruffy, over-long hair (unless fully integrated into your style) has a negative effect on first impressions.
If in doubt get it cut today. Remember - it's the signal that matters, not the effect.
* Nice looking shoes (type doesn't matter, clean or polished does). Men don't care, but ... watch your date's eyes in the first minute or two - 80% chance she'll look at your feet
Conversation matters.
* Don't expect the other person to be good at making conversation. A lot of people expect the other party (you) to do all the work, but will blame the other (you again) if there's a gap in continuity.
Prepare (but not too much - most of it has to be done on the fly, so don't write speeches
.
* Figure out some things to say right at the start, the first time you see each other. Be positive, but don't overdo it.
* Prepare some topics from your existing interests that conform to "dinner party rules". Think about how to open each topic, assuming (1) you start from nothing (a gap in conversation) and (2), you change the topic to yours.
* Listen, and leave gaps for responses/reactions
* Don't just respond yes/no to questions that invite a response. The sporting metaphor is Tennis, not Golf.
* A lot of people ask questions that they want you to ask
them after you've answered. Watch for them - it's easy to ask the same question back when closing your response.
* React to open questions with a
sufficient response. Assume even an open question doesn't invite more than 2-5 sentences. If someone wants your life story they'll let you know via "continuation signals" or new questions.
General
Depending on what you intend to do, there are other considerations, but if you're interested in more, that can be covered in another post.
This is very brief OFC - there are books about this kind of thing, but I'm not planning on writing one here
But generally if you don't make a bad impression in the first 5 minutes, and the conversation doesn't freeze, you can expect that at worst both of you will have a reasonable time, and that you'll figure out if you get along or not.
BTW - what kind of activity do you have planned?
