Trouble with flowing juices (or the lack there of)

I used to be a squirter, like to the point it was an inconvenience rather than a cool thing. I’m talking new sheets squirter. Lately, it’s been the opposite. I’m still aroused the same, still have no issue reaching climax, but with both a partner and my own handy work (HA 😉) I cannot for the life of me open the flood gates.

Has anyone had this happen to them? If so, were you able to bring it back, and how?

Also, has anyone done research on female ejaculate?

Thanks for educating me!
