“…Prior to 1997, sex without condoms among gay and bisexual men was mostly described by researchers as unintentional, some had unprotected sex randomly or inconsistently, others experienced a relapse from safer sex behaviors (Adam, 2005;Adib, Joseph, Ostrow, & James, 1991a;Adib, Joseph, Ostrow, Tal, & Schwartz, 1991b;Adib & Ostrow, 1991, 1995Ekstrand, 1992;Roffman et al, 1998;Williams, Elwood, & Bowen, 2000;Wolitski, 2005). While unprotected sex as a result of relapse or situations in which men intended to use condoms initially but then failed to do so continues, these ''unintentional'' unprotected sex behaviors should be differentiated from the increasingly common ''intentional'' practice of barebacking (unprotected anal sex); (Goodroad, Kirksey, & Butensky, 2000;Parsons, 2005a;Wolitski, 2005).…”
