I am an INTP, yeah.
INFP was my second guess for you, but I think it should have been my first. I must be getting rusty.
There is a correlation between INTPs and schizoid or schizotypal PD. INFPs are not always as different from their thinking counterparts as some assume, so it's not a stretch to say than an INFP could also have a likeness to the two PDs. I could go on to say why they are similar but not sure if it's helpful to here.
Some could argue that schizoids want friends, but... It does kinda go against the predominant symptom of not desiring close relationships. They really don't. If they do, they are possibly misdiagnosed. I know technically they don't have to have that but I'm not sure SPD would be a helpful dx if that were the case. But these are just a layman's opinion, I could be entirely off base here!
And like tiger said, schizoid and schizotypal are all on the schizophrenia spectrum.
