I think Captain Curtis and Lieutenant Boyd would probably be pretty good 'friends', I can see them having some sort of older sister & younger brother relationship. Yes Curtis is a higher rank than Boyd, but I get the impression that Boyd is older and overall has her shit together compared to Curtis.
They fight a lot, maybe it's because they're too similar, but they have to stick together because all the other brass are snobs who exclude them, because they're not senior-officers.
Boyd loves to complain about everything and everyone, including her own husband, and Curtis is more than happy to listen – given gossiping is quite handy to a frumentarius.
In return, Boyd helps him out when he's clueless about something the typical Californian citizen should know – but she just assumes he was overly sheltered growing up, or just stupid. She's definitely not above demeaning a Captain if it means putting him in his place. (In fact I think she'd insult Major Dhatri or even Colonel Hsu to their faces if she thinks they deserve it – now that is something Curtis respects)
Being a legionary, of course Curtis is going to have misogynistic views. He's going to try hide them of course because that puts his mission on the line, but I do think being in the NCR would challenge those views. Curtis would have a lot of respect for Boyd, and maybe even views her as his equal. That makes him doubt his beliefs just a little, but at the end of the day, the NCR are all profligates to him, and it's not like Boyd is just going to 'fix' him and undo all the beliefs he has grown up with.
Anyways, this is how McCarran thinks Curtis grew up
