cum storage for both genders to sell or use or for impregnation or  for your character to drink to boost their refractory rate and quality.  

To be able to create mushroom penis for humanoid options or not only for them

Hairplay: Giving a handjob and using wet hair too

Tailjobs: Giving a tailjob... Also maybe tails that are penetrable on alien-like species. 

At the current build (0.1.10) it is particularly hard to gather Scalium(Green, Pain) and Avium(Purple, Empathy). Chemical conversion can be performed, but the process for one requires the other and an impass is formed. I propose Empathic and Sensitivity Clips, to aide the gathering of Avium and Scalium respectively. They could be anything, preferably early on in the tech tree, and provided it fits subjects with all sets of genitals. This is recommended as a patch in the current system, and if a new mechanic comes up that should make said patch inferior or obsolete I say all the better

It looks like the testicle length slider is adjusting how low they hang, but it seems as though they could still hang a bit lower. Also, you're probably aware of this, but if your character is on the "shower" side the shaft tends to clip through the testicles.

Heavy characters, jiggle physics for fatter body parts. Fat people need love too.

You should be able to pour wax from a candle onto the test subjects.

Scenario 1: Your orgasm-detector isn't working, and one of the female subjects has been dastardly FAKING climaxes! You need to go in and re-calibrate the machine. Set her up however you want, and try to figure out when the orgasm motions she's going through are real; use dead reckoning, use close-up views of certain bits, use post-orgasm stimulation, use whatever -- but get the machine back up!

Scenario 2: Subjects have been climaxing early, because the Edge detection unit hasn't been precisely tracking their pleasure buildup. Some poor subject, either gender, needs to get edged for quite some time to get the thing back on track, using nothing but your wits.

Scenario 3: The automated devices -- vibrators, penis-milkers, whatever -- that are SUPPOSED to automatically edge subjects have been letting them climax early! This is similar to the issue in Scenario 2, and is solved in an analogous way: use the device on a subject and manually turn it up/down to edge them so that it can be calibrated properly.

weve been waiting 17 months for a new update at least give us status reports more often or get a team with at least ONE more game dev to speed it up :( not worth the $10 anymore
