My sister is dating a lovely man who's admitted to her (before it gets too serious) that he caught Herpes off his ex. Now he doesn't get it on his genitals, only to his hand where it gained entry through a cut in his skin. His breakouts happen about twice a year and is only confined to a small patch on his hand, coverable by a band aide.  He also takes medicines for it all the time. Is she at risk of getting genital herpes from him if they have unprotected sex?? She's really serious about this guy but is scared. Any advice would be so welcome. Thank you!
