it's nearly 3 weeks since my DD was born and I feel I'm mentally ready to have sex but don't know if I should physically. I had an episitomy and a few days later some of the stitching came undone and I was left with a gape next to the vaginal opening, I haven't had any soreness for a week but I had a feel and I think the gape is still there, as much as I'd like to have sex I'm worried about doing more damage, how long should I wait and how will I know I'm fully healed?
