Suggest Treatment For Cartilaginous Mass At The Bottom Wall Of Vagina

I am a 19 year old female. I am still physically a virgin, but would very much like not to be. When I try to masturbate or use tampons, it is very difficult and painful for me. I noticed that my hymen seems very thick and doesn't "give" as much as I think it should. Also, I feel like there is a sort of cartilagenous mass at the bottom wall of my vagina that is very painful? Should I seek help from a professional?
