You're talking about it here already, looking for some sort of help. The only difference with a therapist would be that you pay him, and that he or she should actually be trained in properly helping you
THE advice in DAting Age is to meet as much people as possible, to develop yourself, become as carefree and happy with yourself as possible. You said you wanted to bring something to the table for future dates. A confident and carefree attitude is a big something. And it should make dates or relationships a lot more fun.
Now meeting new people and having fun interactions with them (including women) has been made more difficult for you, for whatever reason. So there's an obstacle between what you would like, and where you're at now, right? So remove the obstacle. This is also very much getting out of your comfort zone, in a way that will DEFINITELY help you on the rest of your way. I know a LOT of people wo just had five or six talks with a therapist and had succes.
Now your situation isn't severe at all, but it's still hampering you. Why refrain from doing something that could benefit you? The potential rewards are huge, and the risks completely non-existent.
