I have noticed that a lot of women don't like huge lats though..fwiw. Most like strong looking arms, broad shoulders and a decent chest (although they even complain about that if it's too massive and cantilevering /droopy).
It seems that the best thing to do if you want to be maximally attractive to the most women is to get a low bodyfat and moderate muscular development.
If you want to get into the territory where it's mainly guys going 'omg, check out that dude' then go the whole hog into the strange, homoerotic world of bodybuilding.
