I have several 3 month olds and still can't tell the males from females. They're an average of about 3-4 feet tall and appear healthy.
I find your lack of photographs highly disturbing. Be kind. Perfect your craft. Give more than you take. We are family.
There are no signs of sex on any of those pictures. Last picture is just a expanded joint at the leaf/side stem junction of that node and not a male flower.
The first picture is showing no sex for sure. The thing in the second one doesn't look like a pollen sack to me. I wouldn't toss it just yet.
