you are bisexual, however this should not effect your relationship with your girlfriend. it just means you like guys as well as girls. i suggest you just accept yourself and be happy about it. what you feel is completely natural to you.
torturing someone is very unethical. no one should be tortured or manipulated. people who go to see psychologists need to be supported and helped to get their life back on track. not manipulated and abused. it is very unprofessional and highly unethical.
