How to develop STDs if anyone has one sexual partner and that neither partner has an STD?
How is it possible? I'm just curious about the science behind it.
One reason STDs spread is because people think they need to have sex infected. Wrong. A person can get some STDs, like herpes or genital warts, through skin contact with a region or infected wound. Another myth about STDs is that you can not get it if you have oral sex or anal sex. It also wrong because the viruses or bacteria that cause STDs can enter the body through small cuts or tears in the mouth and anus and genitals. STDs also spread easily because you can not tell if someone has an infection. In fact, some people with STDs do not even know that the have. These people are at risk of transmitting infection to their sexual partners without even realizing it.
