Query the first: My toilet has really stubborn hard water deposits, and no matter WHAT I do, they will not budge. I feel a twinge of mortification when guests need to use the bathroom. Please; send all the advice, tried and true practices, old wives tales you can.

Query the second: (Apologies in advance for how embarrassingly Cosmo this is) So...I am really bad at being on top. I don't know how to ride, and sometimes, I might get the swing of it, but I get tired so quickly! How do I a.) build up riding stamina and b.) ride a dick like a pro?

Thank yewwww!
