CIN2 HPV LETTZ - now what help

I know I sound ridiculous but I really need some help... 

In the space of a couple of months I've had smear, colposcopy, biopsy and LETTZ treatement. I really want to know whether I can still have sex with my partner? 

Will the LETTZ have removed the HPV or not? In which case, if it has, will having sex again with the person just make it come back and I will be back to square one? 

This sounds so silly but I don't see how I can have sex again knowing that it will just happen again ?
