I think it's better to spend more time with this new guy and get to know each other more first. I think it's better to not hand someone new too much private information about you until you feel it's a person you can trust more.

I would hold off a bit so I don't end up having some person spread the word that I am some crazy person with PTSD. I already know that a lot of people simply do not understand what it means and can respond in ways that doesn't even give a relationship a chance. Yes, you struggle with PTSD and you are more sensitive, but there is way more to you than just that.

Sometimes, we can connect with someone where that's more important to the other person than asking them too early to understand that you have ptsd. I have had some time to get to know you better, and you are very intelligent and talented, yes, you have ptsd, but you are also an interesting person with intelligence as well. Better this guy get to know that part of you first IMHO.
