Your impulse control sounds really severe, and you have identity issues characteristic of BPD. Impulse control is also common with ADD.

What about all the concentration and organizational issues though? They can stem from anxiety or depression or bipolar, but have you considered ADD? Are you taking medications? Health conditions ruled out?

Do you have sex to self-sooth or for attention? Does it feel like an addiction?

Concentration and organization aren't normally part of BPD, that sounds more manic if you were having mixed states. But also can come from meds or health issues.
