In case anyone was interested, I have managed some success with the thermoelectric freezing of cum.
I received a peltier thermoelectric cooler in the mail recently, and after several tries, I've finally gotten it to freeze enough to make it work properly.
Problem is that it is bulkier than I intended. But it works. I the cum froze in less than a minute, and after that I took off the cumcicle and stuck it in the freezer. After doing this a few times, I microwaved the them for a few seconds and voila: fresh sperm.
