38 Year Old with 3 Kids Ready to Improve Sex Life

I don't really have too bad an issue down there. I've retained good vaginal muscle tone and am petite. I don't leak urine and self lubricate just fine. I can insert my middle finger and grip without issue. But now I'm done having kids and ready to make improvements all around. Immediately after the procedure my inner walls were swollen and tighter as well as the opening and labia. I can now insert my pinky finger and grip it really well.
After treatment ,I felt and still feel a bit sore as if I've had all night marathon sex. Had sex this morning for the first time since the procedure( I did it yesterday afternoon) and it was a snug fit and he came quicker than usual. If I didnt lubricate as much as I do nautrally, we would have needed lube to get him in.
He is unaware I've done this.
The procedure did not hurt , it was warm but that's it and I do feel a little sore inside but it's not bad.
I'm excited to complete all 3, but am happy with the results from just the one treatment so far. Will update later with how it maintains! Hope it lasts!
