It's a matter of preference, I find it unattractive because I prefer woman who has a bit of fat, too skinny or too much muscle isn't what I would like to see in my companion (I think that my own companion has it's own preferences too). Too skinny reveals a health problem either physical or mental. Too much muscle...Idk it's a preferences that I have, I simply don't find a woman attractive if she has too much muscles. But some woman do look beautiful with a bit of muscle depending on their shape and size but again it's not something that I would like to see in my companion.
