Squirting vs. Peeing???

Any opinions on this topic ladies. Yesterday I started my period and (as usual) got crazy horny. Luckily my man came over and with a tampon inside me, we started messing around.

He kind of just worked his way with my clit when I told him I bought a toy. It was a small bullet and he said he wanted to see what would happen if we used it. Side note: we’ve never had toys in bed. Long story short maybe a second before an intense orgasm I had a huge amount of warm liquid involuntarily squirt out of me.

Never happened before ...

After some “investigation” (my white sheets were yellow tinged and aromatic) we decided it was urine and cleaned up and laughed it off. Definitely new but anyone have ideas on what happened there? Incontinence? “Squirting?” Similar experiences?
