I have the same diagnosis as you Oliveaux. I'm okay with the diagnosis because it really makes sense. For the record though, I just say I have PTSD because BPD has a bigger stigma attached to it.

When they talk about sexuality and BPD it's not intended to be homophobic. Some BPDs do have difficulties with their sexuality in terms of what orientation they are because they are so out of touch with who they really are. And I was extremely promiscuous for most of my younger years and hated myself for it until I found out it was part of my impulsive attention seeking pattern and my need to feel loved and adored even if it was just for a couple of hours.
