As a public health professional with a focus on sexual health, I can provide you with information on how sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), begin. STDs start out when an individual comes into contact with the pathogen responsible for a specific disease. This can occur in several ways: 1. Sexual Intercourse: The most common mode of transmission is through sexual intercourse, which includes vaginal, anal, and oral sex. The pathogens can be present in semen, vaginal fluids, or even skin sores. 2. Skin-to-Skin Contact: As you mentioned, some STDs can be transmitted through skin-to-skin contact with an infected area. For example, herpes and genital warts can be spread this way. 3. Non-Protective Measures: Engaging in sexual activities without using protection, such as condoms, increases the risk of contracting STDs. 4. Bloodborne Pathogens: Certain STDs, like HIV and hepatitis B, can also be transmitted through contact with infected blood. 5. Mother to Child: Some STDs can be passed from an infected mother to her baby during childbirth. 6. Contaminated Objects: While less common, some STDs can survive on objects and potentially infect a person if they come into contact with the pathogen, although this is not a primary mode of transmission. It's important to note that STDs are not limited to any one type of sexual activity or orientation. They can affect anyone who is sexually active and can occur with any form of sexual contact, including oral and anal sex, debunking the myth that these forms of sex are risk-free. Understanding how STDs start and spread is crucial for prevention, which includes regular testing, open communication with partners about sexual health, and using protection during sexual activities. read more >>

One reason STDs spread is because people think they can only be infected if they have sexual intercourse. That's wrong. A person can get some STDs, like herpes or genital warts, through skin-to-skin contact with an infected area or sore. Another myth about STDs is that you can't get them if you have oral or anal sex.read more >>
