Every time I've tried to save my cum, after thawing it out, it always tastes so bad that I usually retch almost immediately and need to run to the bathroom.

I'm no stranger to eating my own cum, but I haven't had any luck with saving it for later. I don't know if it's with storing it, or thawing it out. Normally, I will cum into a shot glass, then transfer it to a little baggie and then put it in the freezer immediately. For thawing, I usually empty all the semen into a glass or similar object, heat up some water, then put the glass into the water like a makeshift double-boiler (so as not to heat it up too fast or overheat it).

Any help?
