Many barebackers employ the strategy of serosorting. Several personal ads on barebacking websites explicitly state HIV status and the desired status of potential partners. Some have theorized that barebacking itself is a serosorting strategy in that barebacking is just a way for HIV-positive men to disclose their status without having to actually tell another they are HIV-positive (Hort, 2000). However, many barebacking ads are from men who claim to be HIV-negative. Nevertheless, many barebackers specify that they will only bareback with individuals of a similar serostatus.
