While I think PCP has a lot to offer the study of sexuality, there seems
to have been very little work in this area (based on a literature search I
did last spring).  None of it, as far as I know, is available on line. 
Most of it can be found in the references of David Winter's book PERSONAL
CONSTRUCT PSYCHOLOGY IN CLINICAL PRACTICE (Routledge, 1992).  I think
there have also been mentions on this list of current ongoing studies
involving PCP approaches to understanding sexual identity and orientation,
but I don't remember the sources or any details--if those people are still
on the list they may come forward when they get back from vacation.
Good luck,
Tim
