I remember our conversation from when you first joined. My body has somewhat of a feminine shape and I attribute it to my body being somewhat resistant to the sex hormones of both sexes. You really should have and need a professional evaluation because if you are intersected, some long range plans should be made and the sooner the better. You are old enough now that you know or will know your own mind and addressing the issue now will allow for the best long term outcome.
I haven't had the more extensive genetic test run on me but everything indicates I am not intersex. For me, there isn't much point in running the more extensive test, but you are young and the sooner you address this the better.
