Hello I and my boyfriend are trying to have sex

Patient: Hello. I and my boyfriend are trying to have sex for the past several months but couldn’t succeed. I was a virgin until I met him last year. I am 27 years old and grew up with penetration phobia and thinking sex as sinful. But now that I plan to marry my boyfriend, we are exlporing different aspects of the relationship. With much pain and effort, finally the vaginal orifice is somewhat opened. I cannot determine if the hymen is still intact (thick hymen) or if my cervix is blocking the opening. I am scared to undergo a surgey. Please help.

Doctor:
