To some extent. My body is naturally quite athletic looking/built but I don't work out. I do however like guys with muscles, but I also don't mind those who are sort of on the same level as I am with a fairly naturally slim/no chub body.
Sometimes yes if the body type is a result of a lifestyle. So I see a lot of fit couples together because they both have a mutual hobby in working out and going to the gym, but some people really don't mind and just like what they like.
Yeah for me. I'm moderately muscular with fat where it needs to be (and where it doesn't) and I'm more attracted to guys who have a fatty-muscular build. That's hard to find since most guys are fat, skinny, or buff.
