Pic 1, I see no signs of sex.

Pic 2, I can see what I think are pairs of whiteish pistols (clearly not the singular spike that can sometimes be confused with female pre-flowers) and would guess female but better and clearer pics are essential to be sure.

Pic 3+4 look very male to me as there are what look very much like big fat balls but again the picsare too blurry to be sure. If they are in small clusters then they are boys, almost certainly.

How long have they been flowering, if at all?
