Gynecologist Help

To whom it may concern,
I am a 19 year old perfectly healthy women. I eat healthy(I am a vegetarian), I excersise, and have an excelent hygine. (I'm sort of a germaphobic). I go to college and have a wonderful relationship with my boyfriend. I have been dating him for almost a year now and we started having sex after our sixth month together. We have not seen anybody or have had sexual intercourse or sexual activities with anybody else. Still I want to go get a check up with a gynecologist just to make sure I am still completely healthy. The downside is that I have not yet tell my parents that I am not a virgin anymore. I am afraid they would not let me see my boyfriend anymore if they find out. So I do not want to tell them. I am under my mothers health insurance and I am affraid if I visit a gynecologist she will find out I am no longer a virgin. What can I do? I really want to make sure I am still completely healthy.
