Genophobia or Fobia of sexual intercouse

I am married with a girl I loved. We married for 6 months and tried to have intercourse at least once a week now. Earlier she allow me to cuddle her and she is passionate about sexual act, but she never allow my fingers to touch her hymen or vagina. She will ask me to abstain from sex during her menstrual cycle. We tried for have intercourse but my wife keep pushing me away everytime my penis near her vagina or hymen. She screams when ever my penis touch her vagina. She strictly never allow me to use finger or allow me to guide my penis towards her vagina. Its difficult to make her open her leg and change her position of sex except her flat supine position during "Sex". She never had any past trauma on sexual matter except her influence of story of her twin sister who was complaining about sexual intercourse pain to their family. She also might have influenced by her friends who mention that sexual experience are painful. She is a nurse and understand anatomy of sexual very well. I am a perfusionist who have a good background of medical. Should I sedate my wife to have intercourse? Please do advice me.
