Many times.....
The last time was accidental (2 days ago), I shot a stream into my face (luckily I was wearing my glasses, because I know how it stings if it goes in the eye) and some went into my mouth and onto my lip.
When I was about 17 or 18 years old, I decided to save it in a wine glass. I used to whack off several times a day in my teens and 20's ( 9 times in 1 day was my maximum ) over a few days I had quite a bit in the glass, but when I came to drink it the smell put me off. The first few loads had begun to separate, becoming quite clear into which the newer stuff floated...... I did have a sip but I don't recommend tasting after its BEST BEFORE DATE.!
