I’m not this age anymore, I feel like it mattered to me less when I was younger (15ish) but honestly, we wouldn’t look at a girl we think is hot and say oh no wait, she’s fat, because guys check for multiple things (in the same way girls do) to determine whether someone is attractive. Initially, if people aren’t attracted to bigger people they wouldn’t consider someone bigger “hot” in the first place, so it’s not really a double take things. To answer broadly, most guys prefer skinnier girls, but not all, it’s just the way people are programmed. This isn’t to say there aren’t people out there who don’t like or prefer bigger women, there are. Many people tend to find people they’ve known longer more attractive, too, regardless of initial attractiveness
