Condoms and dental dams help prevent sexually transmitted infections (STIs), including HIV, from being transmitted between sexual partners. STIs can be transmitted between partners during different types of sex without a condom, including anal sex, vaginal sex, and oral sex.
Then no matter how thin condoms are now, there is still a difference in feeling from not using condoms. Not using condoms can make you feel more stimulated and comfortable during sex.
Having sex without condoms can carry certain risks depending on how many partners you have and the type of sex you’re engaging in.
