Hello dear I understand your concern The more common causes of herpes transmission: kissing, or direct skin-to-skin contact during vaginal, anal, or oral sex with someone who has an active infection. It is possible, however, to spread the virus via the fingers including manual stimulation and masturbation. Transmission of the virus via routes like sharing bed linen, clothing, towels, toilet seats, eating utensils, shared cups/glasses, and in public spas is less likely. So I think it is come mainly from the sexual contact from the partner. You can ask your partner to test for herpes to find the infection. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
