Tmi post - help!

So like 30mins ago I finished masturbating.

Laid in bed for a bit longer just chilling on my phone.

Came downstairs to make breakfast and walked around for a bit

And then my vagina like contracted and then like “pushed” and it started feeling rly wet so I quickly went to the bathroom and there was all this goopy stuff in my underwear and lots when I wiped.

What is it??
