Did you read question #14 of the HSV FAQ? You could have saved yourself ten bucks, this website even forces you to read that before you can even post... cheers mate.
As others already responded, your questions have been addressed. Nonsexual transmission of genital HSV infection (whether HSV-1 or -2) has never been shown to happen. If it does, it is exceedingly rare. If contact with toilet seats could spread herpes, people would show up in clinics with rings of lesions around their buttocks and thighs. Anyway, HSV probably has to be massaged into genital tissues for there to be a significant risk of transmission, not just applied to the surface of the skin.
As for oral (HSV-1) infection, common-sense hygiene is all you need to worry about. In particular, if you're having an oubreak of symptomatic cold sores, don't share glasses with people and don't kiss anyone.
Good luck-- HHH, MD
