###Human: How to protect myself from STD? ###Assistant: Hi. I appreciate that you are very much conscious and alert while having sex and take all preventive measures. 1. Kissing can spread some diseases only if the other partner is infected .These diseases spread through saliva . There are so many diseases which spread through kissing like mononucleosis, certain kind of viral infections and sore throat and some other. I guess you are much concerned about STDs (Sexually Transmitted Diseases). HIV is present in saliva but till now no HIV case had been reported through kissing. But hepatitis B cases are reported and well documented and hepatitis A & C as well, so here I will advise you not to kiss women about whom you are not aware of their health status. 2. Herpes viruses are of many types and can spread through skin contact also. Here I think you are concerned with genital herpes virus which causes STD. This usually spreads via sexual intercourse but can also spread through body fluids like blood, saliva, oral sex (without a condom) if your partner is infected. 3. No, there is no vaccine available for herpes. But you must get hepatitis B vaccination done as it is a fatal disease. 4. If you are using lubricated condoms then no need to use a lubricant unless your partner is not comfortable without a lubricant. 5. Anal sex is usually not advisable as it can cause intense pain and injury inside your partner's anus and not safe for her. But if you insist and want to do, then apply a lubricating gel and can do at your own risk. 6. Washing genital organs after having sex is advisable.
