I work with all girls, they sit around all day and talk about big dicks and google them,,,who wants to be average? We would refer to a guy with. slightly above average (of all humans) physique as a twig or lard ass. Girls call a dude with just an above average cock, small.
But back to body size. All of us have a size where we are most attractive to chicks. its not starved 140 (assume 5ft 10) but if you think its up over 210 to closer to 180 id say based on my experience and conversation with women, you are way high.
Look at female models, actress, their level of muscle, fat size. They do that profession because that is close to the "ideal". Look at the same for males.
I think what you think chicks want is way more muscular than the truth, google it. Sure there are fitness chicks who have a muscle fetish and there are guy who actually would fuck muscle chick and Rhonda rouseys disgusting ass.
But the physique that appeals to the MOSt chicks meaning gets the most pussy, is not over 200lbs you can google it.
