Should i go see a therapist ?need advice ?

I am 21 Years old and I feel that when I was younger I was molested.I know you may say well how do you know.well there are something that I have been dealing with sexually that I don't feel that's normal for a young woman.What many women enjoy I find painful and unbearable.I get these strange emotions out of nowhere when I have sex.I hate to have any man including my gyn to touch me down there I through a fit.there has been many times I went to go get pap smear and I started crying uncontrollably for some reason and the nurse asked me have I been raped and I said I didn't know but I was crying.It triggered these strange emotions inside of me that i couldn't control.what should i do?
