I have the same feelings as Raynaadi. I'm a straight woman but lesbian porn turns me on too. Don't know what it is about it.. probably just that it's different.

As for the PTSD stuff, I suffer from that as well.. there is the forum for that, but if you aren't seeing someone about it (therapist or other doctor) you might want to consider that. Sometimes things happen in life that are just too difficult for us to handle on our own.
