Heya Anthony! I had electrocautery, although to the vulvar region. The thing about it, as it probably is for any wart removal procedure, is that you're going to need to allow it time to heal. This means that you're going to have to go without for a while =P Well, at least in regards to anal play; petting the one-eyed monster is still, obviously, fine
It takes about a month for the wounds to heal properly and completely.
After that, I think it would be fine to receive anal sex---I would say just try to avoid being too rough just because of the fact that the anal mucosa is very thin. To be horribly scientific (blame med school), the vagina is stratified columnar epithelium (it's thicker layers of cells). However, the anus only has simple squamous epithelium---it's only one (small) cell layer thick. This makes it prone to tearing and injury.
Just be cautious and safe! Let us know how it goes.
