to understand the attitude of men who have sex with men (MSM) towards the use of condoms, to identify potential barriers to their use, environmental factors that facilitate or on the contrary, prevent this use, beliefs about contracting HIV, and priority needs of MSM for general prevention of sexually transmitted infections (STI). Individual interviews conducted in private with 20 MSM. In general, MSM recognize that condoms protect against STI as well as preventing unwanted pregnancies (although this is not our purpose here). The disadvantages of condom use that they reported included the potential for them to break and their reduction of pleasure. Barriers to their use include the belief that the partner is not HIV-positive, the shame of buying condoms, inability to wear them, and lack of financial resources, as well as social norms and false beliefs. MSM are aware of the positive role of condoms against STIs, including HIV. They perceive the dangerousness of the HIV, but do not feel vulnerable to this disease. They have identified obstacles to condom use, and their lists of perceived needs suggest solutions to them. Implementing these solutions in interventions should improve the frequency of condom use.
