They are by and large pretty pro-blowjob. Daniel could care less about receiving them probably, and I’m not sure Skip is super into them (I’m increasingly sure that Skip is asexual), but other than that I’d say everyone is pretty onboard with receiving blowjobs.
As for giving them, Cal particularly likes it because he’s good at it, and Isaac always likes doing it too. Gavin is fond of giving and Pax and Nate do more blowjobs that almost anything in the bedroom. Ron also looks forward to giving them to James. Edwin is very proud of his blowjob skills and wishes that Erik would let him show them off more often. I can’t really think of anyone besides Sam who’d object to giving a blowjob. It’s not Marcus’s favourite thing, but other than that, everyone is pretty okay with giving too.
So yeah, by and large, it’s a pretty pro-blowjob crowd, I’d say.
