Of course! I originally saw your post on mobile and got about 2 sentences in before I realized I needed a keyboard and cracked open the laptop. Glad the infodump was helpful!
A few thoughts here - man, do I understand the sense of "if I can’t do it [perfectly] the first time I’m not sure I want to try. Resiliency is hard for things that can’t be completely prepared, rehearsed, and controlled for me, too. But I also know that the first time my wife asked if I’d be willing to run a marathon with her we didn’t go out and run 26 miles. We started training by adding 1 mile to our base at a time. She didn’t bail on me when I needed a rest day the first time we broke 10 miles, or needed to stop and walk 15 miles in.
So have fun with the prep conversations! It’s great foreplay. Definitely gets me going when we stop to plan how we’re going to spend sexy time together. It’s like an outline. Sometimes when we roleplay I’m like, “I don’t have a script, I don’t know what I’m doing, do you have ideas of what you think should be included here, generally?” And then I have leeway to connect those dots creatively and know I’m not completely biffing. So prep talk, or writing. And then I like to debrief after any session that pushes our edges - usually it’s the afternoon, and we’ll get dinner after. Nothing like getting cozy in a restaurant booth and asking, “How did you like this? What did I do well? I didn’t think this worked… how’d it feel to you?” over tacos and margaritas. And less intimidating than trying to debrief while still in bed, though we’ve also had good debriefs as pillowtalk, too.
I’m hopeful you hear this in the manner it’s offered, but it does sound like your wife chose you before a diagnoses - warts and all! All the diagnosis changes is your ability to think about how you see your warts: not as something wrong to be fixed, but an inherently connected to the whole way you’re wired. And since it’s a spectrum, it’s all woven together and connected and pulling at one might destroy the other. The wiring that makes interpersonal behaviors exhausting or challenging is connected to the wiring that allows for pebbling, hyperfixation, deep knowledge, and identifying the interconnectedness of things. It’s the wiring that means when you really let someone in to know you they are really in because you suffer no fools or surface connections. You can understand me with intimacy or not at all. Anyway - that’s a little bit of my personal understanding anyway.
So tap into your ‘tism superpowers and deep dive (like you’re doing). Use the forum like you’re doing, find examples of dirty talk, pose the conversations with your wife - “I’ve been thinking a lot about your request for me to talk dirty to you, and I’d like to work on doing that well for us. I have some questions!” Ask her for examples. Find lists of words or suggestions to read together. We’ve had things that until we read them aloud together and heard them coming out of each others’ mouths had NO idea it was a turn on.
And we are still discovering new things over 20 years in. The other week we were having a longer romp and she was on her knees going down on me, I was talking dirty and pulling her hair like she likes, and she lifted her head and looked at me and said, “would you slap my face with your cock?” Never before has she asked, never before have I thought of it. I don’t know how long she’s wanted it, but I know she was willing to ask for it and so we tried it.
I listen to a sex/marriage podcaster who would say that there is no intimacy without vulnerability and no vulnerability without anxiety (not his quote, just how I think he’d respond to the way you put it). If you want to go deeper into intimacy you have to be vulnerable and if you’re not feeling anxious about opening up vulnerably, is it even vulnerable? And then when that vulnerability is met with love and grace and acceptance, it smooths over the anxiety and says “I see you, and I love you” and that’s intimacy. And the deeper you want your intimacy to go, the more anxiety you’re going to have to dig through in the name of vulnerability.
You got this! Have fun!
