I have.

I had a CIN3 result, they did a biopsy, then booked in for a letz procedure. They had removed approx 90% of it when they did the biopsy but because it was a CIN3 they had to do the letz. It was morning surgery and I was back at work by lunchtime.

I then had to have 6 monthly paps for 2 years, then they gave me the option of double screening, which was if that came back clear two years running I'd be back on two yearly ones. I've been on two yearly ones now for the last 3 times (due for one now)

Yes you can get HVP from one sexual partner, my big sister did at 19 and she'd only been with one man.
