do you think it's weird?

Do you think it's weird when a guy thinks someone who's pregnant is like really hot? My boyfriend and I were talking about it cause he thought my bump was sexy and that I understand if he thinks I'm attractive cause I'm carrying his kid. But he was talking about how his friend thiught this girl was hot then when she got pregnant he was like obsessed with her. Like talked about how he'd want to have sex with her. And I even had a guy I use to talk to try to hit me up for sex and I told him no I'm pregnant with my boyfriend and he pretty much didn't care and said he wants to fuck when I'm pregnant(I just ignored him cause I wouldn't) but I just think it's kind of weird a guy thinks a girl is like super hot and wants to fuck her when she's pregnant with another mans baby lol.
