Dear community, I have read alot of information about herpes transmission online but am getting stuck with this issue. Most sources say that HSV is spread by DIRECT CONTACT between lesions or fluids of the infected individual and mucosal membrane/abraded skin of the recipient. Then other sources say that condoms are not 100% effective (they only reduce the risk by 30-50% for the man) because they don't protect areas not covered. Then there is the statistic whereby a discordant couple have a 2-4% probably (can't remember exactly) of HSV transmission a year even when condoms are used. I have several related questions.
1. The scrotum is not considered to be a mucosal membrane, right? So if someone with oral herpes performed oral sex on the scrotum, or if the female membranes rubbed against the scrotum during sex, the virus should not be able to enter through the scrotum?
2. I am surprised/worried that even with condom usage there is still a significant risk of transmission to the male. If the above regarding the scrotum is correct, then the head of the penis (glans) is the only part of the male genitalia (excluding anus, but I don't plan on involving that part in sex) with mucosal membranes, right? Does that mean that there is always some broken skin near the genital area that the virus succeeds at getting at?
3. Related to the questions above, how can I reduce the risk of contracting HSV either via oral sex or intercourse when a condom is on? Avoid oral sex on the testes/anus? Wear shorts to cover up rest of skin and only expose the condom-covered penis?
4. Can HSV1/HSV2 enter through other parts of the body except for the mouth/genitals, and if so, what happens? For example, if an HSV positive individual licks my nipple, and there was a small cut that I didn't see there, what could happen?
Thanks in advance!
