With this sort of start to a thread, you cant seriously expect a full physical and personality lesson on what most girls are attracted to which an alpha male like myself could give you. however, the very fact that you have no clue where to start and seem to be lacking in the communications and confidence department, that would seem to be a good start. talk to girls first. when you can do that, confidently it will come much easier to recognise what they like. you must remember that not all girls have the same type, so perhaps you have not met the right one yet.
however, I know for one that a lot like good body (broad shoulders), nice hair, nice body, can hold a good convo, make them laugh, etc etc. some like to stick to the typical: talk, dark, handsome. however, you have to make the best of what you got. so, my son, got get em.
