Condoms greatly reduce the risk of getting or passing on many STIs, including HIV, if they are used correctly each time you have sex or share sex toys. Condoms come in many different types and sizes. You can try out different kinds to see which feel best to you. It is important to know that only latex and polyurethane condoms are effective at preventing transmission of HIV and other STIs. Other condoms, such as lambskin condoms, do not prevent the transmission of HIV and other STIs.
Internal Condoms
Internal condoms (also called female condoms) are polyurethane condoms you can put into the vagina or anus before sex. Although they are often called female condoms, they can be used by people of any gender for anal sex.
Types
Different people prefer different kinds of condoms. Whether you like condoms that are flavored, unflavored, internal, external, latex or polyurethane, the important thing is for you and your partner(s) to decide which are best for you and to use them every time.
Lubricants and Spermicides
Two important notes on lubricant and spermicides and condoms:
- If you are worried about your risk of HIV and STIs, spermicides, such as Nonoxynol 9, should be avoided. Spermicides, and condoms with spermicidal lube, can cause irritation of the vagina, anus and penis. This irritation increases the chance of getting or passing on HIV and other STIs.
- For vaginal sex (and for oral sex on a vulva), it is best to use condoms or lube that are not flavored and which don't contain glycerin. Glycerin can make yeast infections more likely for some people.
