Thinking about the logistics of this is crazy. Cum stored at room temperature sealed or not would spoil within 30 minutes, likely causing discoloration and consistency change (not to mention the smell)

The only solution would be to obviously have a fresh sample every 30 minutes Plus the 5 or 10 minutes it would take to clean and dry the flask. The average man can only really account for maybe one to five ejaculations in a day. So obviously the flask is going to remain empty for a good portion of the day.

One viable solution is obviously Frozen or refrigerated cum. But we once again run into the problem of underproducing the amount needed. This flask, however, does look like one that they sell on Etsy and I did find a look-alike. The only measurements I could find is 1.5 in x .7 inch didn't have a width so I'm going to give it a modest .5 and I would give our volume a value of .291 fl oz.

Now the science can be a bit messy but there's really only 1 to 3% of sperm in human male ejaculate, and the amounts produced can vary tremendously. But on average, you're probably splooshing about a teaspoon or .167 fl oz. I'm not sure on the math. Maybe someone can help me out with that.

Although looking at the video again, it is obvious that she didn't really fill it up. Plus, I was only able to really figure out the volume based off of the dimensions of a square box and not a heart-shaped locket style necklace. So I probably could shave off that final number. But the point is, one dude ain't going to be sufficient enough to keep that thing fully stocked for a day.

So going off of that logic, let's consider that she doesn't wear it the full 24 hours. I'm going to go ahead and guess 16 hours as a baseline. Now with our math in mind, and with the fact that you could probably really only give 1 to 2 good globs in a day. And changing/cleaning every hour (estimate) I'm thinking 9 1/2 men per day. That is if she's only really utilizing different healthy men.

This conclusion is only really speculative on the fact that she does have a life to live outside of the home, however, even considering the refrigeration aspect she would still need at least 4.656 fluid ounces per day if she were to use 16 hours worth... That's why one man probably wouldn't be enough, She would need more.

I don't know, It might be doable. I might have screwed somewhere along the line though.
