Re: HPV and no sexual contact?
Sure you can get it w/o sex! HPV includes ALL strains of the virus, not just the kinds that are transmitted sexually. e.g. there are tons of kids running around with warts on their hands or feet and nobody is claiming they got them from sexual contact. I had a wart on my leg as a youth and certainly didn't get it that way.
Sexual contact is probably the best way, since there's waaaay more physical contact (and if she actually had a case of genital warts, the conection would be obvious) but it's certainly not the only way. It just means that she had some kind of physical contact with someone with the virus.
