Thanks for your care and concern. As you may know Herpes is a sexually transmitted disease which is spread mainly while the outbreak is on. While you are the outbreak of it, you will feel itching, tingling and get similar sensations. These symptoms are called prodromal symptoms. Those symptoms warn that there are viruses inside the skin, which can get transmitted to others while having a skin to skin contact. From your question, it is evident that you got the outbreak about one year ago and there is minimal risk in transmitting the disease to your wife. Hope your doubt is cleared. Take care.
