Answer:
Sexually Transmitted Diseases
Explanation:
Sexually Transmitted Diseases (or STDs) are diseases that are transmitted through sexual intercourse. The risk of contracting such diseases, is a factor that influences a person's ability to not have sex.
While some STDs are treatable and curable, there are others that do not have a treatment, such as HIV/AIDS, Hepatitis B, and herpes.
All these STDs are transmitted through sexual intercourse, and are not treatable.
