Novice faggot news’s advise re: piss play

Dear Sam,

your work has changed my life as I've come to better understand my role and place as a sub faggot bottom boi, and I've had several wonderful opportunities to be my true self and serve a man over the last year. I'm so luckily to have a visit with an Alpha in the Midwest next month. I can't wait! He emphasizes that I will drink his piss. Thing is I've never done it before and have no interest. I know that shouldn't matter. A previous Alpha made me run his ass, and I came to appreciate how lucky I was to do it and that his pleasure was my focus (it always is).
So, any advice for overcoming my aversion? How should I navigate? FWIW I love manly scents, cum, precum. Please help.
