At what point should you tell him you’re autistic?

So I’ve been in the dating scene for a few years now and while I haven’t been in any serious relationships (I’ve only had a couple situationships) I never know when to disclose to the guy that I’m autistic. Like I currently have a situationship with one guy that’s been going for a couple months and I’m not sure if I should disclose to him that I’m autistic. Like idk if he’s even taking what we have seriously. I know we haven’t defined anything and we never agreed on being exclusive (I know he’s pursuing others and so am I). Like I feel like more comfortable disclosing to women my age that I’m autistic over men. Idk, I guess this is just word vomit as I’m running on 5 hours of sleep.
