Swelling

I have had sex many times but not for about two years. The other day I was trying to use a jelly dildo but when I tried to put it in I had to stop because it hurt so much. I also haven't been able to use a tampon for a couple months. And the inside of my vaginia feels swollen. I had an OBGYN appointment s couple months around and everything was fine. Has anyone else had this problem?
