I’ve known people who are autistic who were dating coaches, and quite successful ones at that
Now the things that I would say are the least relevant are your being autistic and lack of experience. First and foremost, I think people overestimate the impact of “experience”. There are benefits to dating experience in as much as you know yourself and your patterns in relationships, you have a handle on what you want and you’re a little more secure in the bumps and potholes that crop up in every relationship.
Someone who has only ever dated their high-school sweetheart and were married for 30 years doesn’t have a “lot of dating experience”, but is doing just fine
Now, there may be people who might not want to date you because that lack of experience may mean that you aren’t sure of what you want out of a relationship, or who may worry that this will mean that you’ve not had all of the ‘experiences’ that you wanted (that is: banging lots of different people).
