It doesn't bother me at all - usually I'm not a huge fan of really muscled guys. I mean, sure I like the look of it - but in real life - meh, most the guys I've been attracted to haven't really had any.
I don't know - it's not something that worries me. As long as a guy isn't overly skinny (it just doesn't so it for me) then I'm good.
I don't think girls necessarily want the "jacked" dudes you see on reality TV but they like a toned/fit guy. Having no muscle tone (I'm guessing this is what you mean) is not a positive but most girls would be OK with it having seen what I've seen on this site. At that point it's important that you aren't overweight which is a big no-no.
