African Americans are overrepresented among heterosexual cases of HIV/ AIDS in the USA. Inconsistent condom use and concurrent partnering are two sexual behaviors driving the heterosexual HIV epidemic in the African American community. To inform the development of an HIV prevention behavioral intervention to decrease concurrent partnering and increase condom use among African American heterosexual men, we conducted formative research, including 61 structured interviews, 5 focus groups with 25 men, and 30 in-depth qualitative interviews between July and December 2009. We used a grounded theoretical approach and categorizing strategies to code and analyze the qualitative data. Results around condom use confirmed earlier findings among heterosexual men in general: condoms diminish pleasure, interfere with erection, and symbolize infidelity. Although valued by some as a form of disease prevention and pregnancy prevention, condoms are often used only with specific types of female partners, such as new or casual partners, or due to visual risk assessment. Sex partner concurrency was described as normative and ascribed to men's "natural" desire to engage in a variety of sexual activities or their high sex drive, with little recognition of the role it plays in the heterosexual HIV epidemic. Fatherhood emerged among many men as a crucial life event and compelling motivation for reducing sexual risk behavior. Based on these results, we conclude that existing HIV prevention efforts to improve attitudes towards and motivate use of condoms either have not reached or have not been successful with African American heterosexual men. In designing behavioral interventions to decrease concurrent partnering and increase condom use, addressing negative attitudes towards condoms and partner risk assessment is critical, as is integrating novel motivational approaches related to identity as fathers and men in the African American community.
