White Fluid Discharges?

So last night I was sending sexy pictures to my S/O and getting some back, I wasn't touching myself or anything because I merely wanted to show off 😂😂 however, i felt water drip on my thighs so I looked down but instead I saw a white watery substance?? It literally looked like milk?

I've never had this before and it just threw me off. I have no idea what it is...

Any opinions? Thoughts?
