Is this man hitting on my husband?

I went to a staff Christmas party and one of my coworkers brought her brother. We were all talking about ex's. My husband mentioned his ex wife that demanded he marry her 5 months after dating. This guy looks my husband in the eye and said "I'm not one to believe in demands. I find consent quite sexy." My husband just let out a small laugh. I tried to brush it off. Then me and my coworker were a court of thorns and roses(smut book). Her brother said he only read the first one because he's over hearing"straight people being horny" and he thinks the sex in it is trash and he could write better. My husband said he just doesn't enjoy smut. The brother said "I guarantee you like what I have to right. I have a talent for making people horny." He just stares and smiles and my husband and my husband just turns red and looks away. At home he said I have weird coworkers. I told him her brother was clearly flirting with him. My husband doesn't think so and thinks he's just odd... But I think he was and found it uncomfortable
