Hello, I've started masturbating with a vibrator and I feel deep shooting pain and it's very hard to explain, I'm not exactly sure where but it feels like it's in the lower back and the rectum and i also have pain when pressing around my lower butt and pressure in the rectum, I've been to a gynaecologist for a regular check up and the ultrasound and and swab were clear, but she did find that I have a cervical erosion and I will get surgery for it, but the pain isn't in the lower stomach it's in the back and I'm not sure the erosion is causing because it started after my visit to the gyno.
Also it feels very uncomfortable and unlike “normal” from friction or deep penetration, as if I’m stabbing my tailbone.
