I'm aiming to drink at least a liter in one video and don’t feel comfortable discussing this with my doctor. Just 100mls or so contains your daily required intake of zinc and too much zinc can have some negative health effects. But am I damaging myself by not taking my body’s prompt to throw it up? From the research I've done, it seems the zinc in cum is the biggest worry. Second question, how much cum is safe to drink? And digest? It does give me an upset stomach, but I can usually handle that. First, could STDs/STIs survive the freezing-and-thawing process? I've already drank a few glasses of his cum, so that boat has already sailed regarding my current “cumbull,” as they’re known in my niche sexual community, but I'm looking at getting more donors. It used to just be my own that I saved up over time, but I met a guy online a couple years ago that's into feeding his cum to people like myself. Since I don't have a stable of guys to supply me, I use frozen cum. I make and sell videos of me drinking large amounts of cum. I say “drinking” and not “swallowing” because I'm talking about glassfuls. I'm a 40-year-old bi guy, and I’m really into drinking cum.
