Is it normal i have this feelings regarding my bisexual girl friend?
I am a straight man, and my girl friend is bisexual. I have no problem when she mixes with, plays with and sleeps with other bisexual/lesbian girls, Infact I encourage her to go out with them and even introduced her to a lesbian cousin of mine and they still see each other. She also introduced me to some of her other bisexual partners, and I had a one night stand with most of them too. However I cant stand the site of her with another man and if I ever see her chat with one I want to kill him right away. She was very friendly to some of the guys at college and used to chat with them a lot, but after I explained how I felt and even threatened to break up with her she doesnt talk to them anymore. I made her promise never even talk to another man excluding her father (who is a nice old bloke, and accepts our relationship) and myself, and she agreed cause we truly love each other and wont do anything that may cause us to lose each other. However I assured her that I have no problems with her hanging with other girls. Once I even beat up my younger brother (who was 13 then) who once played truth or dare with her, and when she chose dare he dared her to kiss him. She ofcourse took my action reproachfully but knew how I felt so dropped the matter, and I threatened my brother with sever beating if he ever looked at her again. Does anyone else in this situation feel this way?
