I will save my rant on why it’s weird to talk about “active” and “passive” partners in oral sex for another time, but if I understand your question correctly, the answer is: It’s unclear. Take it with a grain of salt, as you should anything you read on Reddit, though funnily enough, Reddit is about the most bountiful source of anecdotal cumsicle information.
I read a Reddit horror story of someone who ate two weeks’ worth of frozen cum and had intense diarrhea as a result. Since you have already taken STDs out of the equation, thus eliminating the chance of spreading a localized infection to another part of your body, the main thing to be concerned about is whether you have a semen allergy-it is, in fact, possible to be allergic to your own semen, and this may present as redness, swelling, and hives. So let’s ponder the risks of semen eating more generally. Even though this involves adding a preservative and is generally a far more sterile process than the average puttering around of the kitchen, we can assume that what comes out of the freezer is more or less what comes out of the dick. Through the cryopreservation process, sperm that is frozen and stored can be thawed at a later date for fertilization. While those who frequent the more fetishy fringes of tube sites have likely heard of this practice, for obvious reasons, there isn’t much data available to help us determine the risks involved in becoming your own Mister Softee machine.
