Showing sex?

Hard to see exactly, one clear close up picture would help, as unfortunately there is no "zoom" function on this platform, however, yes, it looks like pistils in picture 1 and female calyxes in picture 2. Look for small white hairs (pistils) emerging from pods (calyxes) growing at the junction of the main stem with a leaf or branch and this will confirm your suspicions that they are indeed female plants. The time frame for an auto seems about right for it to start flowering. Male flowers will be similar in size, but have a smaller lower portion of a pod, with a larger rear portion of a pod that will form a type of curved "brim" overlapping the lower portion of the pod, or a bit like the lower portion of the pod is wearing a hoodie, if that makes sense. In time, the male flowers will grow a stalk, then form a cluster of male flowers on top of the stalk, making it easy to tell that your plant is male. Also, male flowers will have no hairs/pistils emerging from within the "pods", but stay closed until mature enough to shed pollen. The separate segments of the male pods/bracts will then peel back like petals on a flower, exposing the male stamens, or bananas as people call them, to the air, allowing for the pollen to be swept away by the wind in search of female pistils to land upon and fertilize the seed ovule contained at the base of the pistils within the female calyx.
