Bigger Dick doesn't mean better sex, man. Yeah sure it helps but after a certain length, it's useless.Of course, but let's not pretend that it isn't a major factor in whether relationship works out or not. Plus "reliable, responsible, has better job and brings me money" is a very cold/cynical/utilitarian evaluation of a person and not really good basis for romantic relationship either, unless maybe with similarly benefits-oriented partner who doesn't mind being perceived through such lens.
