I had a rather painful session of sex two days ago as my partner inserted something big with a flat bottom inside my vagina despite my protests. Now two days later I noticed a sweetish smelling and more curd-like appearance for my vaginal discharge so I inserted my fingers in, and felt a large opening right where the bulge of the G spot should be. It's so large I could push a finger in and go in further for a bit but I stopped as I was afraid of hurting myself. I did not experience any pain after the insertion but there is a large amount of sweetish smelling curd inside my vagina. Is this hole a cut made or should it be there? I'm slightly worried and I hope it can heal on its own within a few days if I lay off sex. Any ideas what's going on?

First change partners ( did not say boy or girl friend) if they continued to something sexual after you said no, you should never be with them again.

Next, you need to go have this looked at my the doctor

Actually I've looked around online and I can't be sure if it's actually just a swollen cervix.. my ovulation date is around now and the ball with a hole I felt is about 3 inches up. I'm not sure if cervix should be so low down though and the sweetish smell and mustard-like sticky discharge feels all wrong..
