Can I use monogamy as a long-term protection against STDs?

Only the complete absence of sexual contact can be a truly reliable protection against STDs and HIV transmitted through genital or oral contact. However, monogamy and a limitation of the number of sexual partners can also be effective prevention if adopted in the long-term. If you give up the practice of monogamy at any time and acquire several casual sexual partners, you will increase your risk of exposure to STDs and HIV.
