We are similar in the sense I stutter profusely with my family (specifically parents) and am almost 95% fluent with my friends. Funny you also mentioned a "masked version". I can relate a lot to that. My wife who was my GF at the time - I attracted with my masked persona. But overtime, I opened up to her and she was accepting of who I was. As practical advice, if you are unable to even initiate a convo with a girl as your genuine self, try to engage her with your "masked version", but then quickly open up either via text or in some way comfortable to you - to let her know about your speech and true self. This will give you a good judgement if she's worth it. Because anyone who is going to dismiss you because of your speech and true self, is not someone that's worth keeping as a partner.
