Ok will do. Do the males have to be removed before going 12/12 or shortly after?
Males need to be removed before they can pollinate the females.
Males create pollen sacks that fill and eventually burst tossing pollen into the air. When that pollen makes contact with the pistols of a female, it sticks. Eventually that pollen makes its way into the calyx(female's little sacks that produce the seed) and then continue to form a seed with the genetics of both male and female plants.
Males aren't "dangerous" until pollen is created, which is within a few days of the pollen sacs forming. Typically the pollen sacks aren't overly sensitive when they are young so as long as you aren't bashing the plant around when you remove it you are ok.
You can wait until you can confirm sex and everything will be just fine.
In my experience, the males tend to produce shorter and less pointy of those little jagged things in your pictures. Everytime I've seen those, within a week or so into the 12/12 I start seeing sacks with hairs form just behind it. All the males that I've ever identified (only a handful) they didn't really have those little pointy things, and the sacks form before, or very early into 12/12.
I've also had a few females show pistols before 12/12 but they usually only did that if I accidentally stressed them out.
