Many classes tend to be about "patterns", "patterns" and yet more "patterns" and leader-based. Maybe worth investing in a short programme designed for followers technique only or even better, a class where a couple are teaching in which they tend to separate the class with "men over there and women over here" (but NOT travelling teachers, however, as their focus too tend to be leader-based). Also (as I advised a recent beginning follower at the weekend) ask your teacher for a dance come the milonga and also target a (good) female lead if you happen to spot one. What I do is lead a follower who has been sitting for too long mainly to show her off to the guys that have been ignoring her. That way they get to see her dance and eventually ask her (several cases in point at a milonga last Sunday).
