He's wearing condoms with guys now because he wants to collab with girls more now. He's appeared in some girls' OF videos uncredited and unpromoted without condoms. Female sex workers don't feel safe working with crossover talent, especially those who do BB with other guys. Steve Rickz has admitted as much that he only shoots with guys that do crossover work as well (Roman, Cliff, Hatler, Dante, Justanice, etc.) because only those guys can be trusted even with testing, which is what allows them to do bareback with girls and those select guys. I'm assuming he's just parroting what the girls are telling him on the side, and that's why Blake is following suit.
