IMO, not safe at all if warts are visible.. it there are no warts, no lesions or other tender lumpy things that can get open go for it.
Cuople of months ago, I'd have probably said it's all safe, whatever you do, considering that people have much more sever condition than this common virus. But, I read in this board about a woman who was infected with HPV (the high risk strains) and she got tonsil cancer beacuse of HPV! She did not know which speccific strains caused her that, and it might be entirely unrelated to our condition, yet something to think about. I don't want to freak out anyone, just something to keep in mind....use your discretion when both giving and recieving
