I'll go first. No, but I wish I had!

No. Ten year gap between losing my virginity and losing my wam virginity.

I began wamming just before I reached puberty. The first time I came was the result of playing in some slippery substance and I had no idea what had just happened. I have no idea why I started to want to get messy, but it began as a phycological thing but then quickly turned into a sexual thing.

My first orgasm involved smooth peanut butter, I didn't quite understand what was happening, but knew it was really nice. Hooked ever since

My ex wasn't a WAM fan, so we never did anything. Since then, I've been with a few girls who are accepting of it, and it's fun to use.

My wifie lost some type of virginity when we used gunge for the first time on her lolz

Her first time using a double ended dildo

I'd "gunged" myself on the sly, with custard a few times before and through my teens... I had no idea how to bring that subject up with someone else, until I went for it one day at the age of 38 with my wife... we've had messy fun since.

Lol nope still not happened.
