So maybe alcohol swab over my head and part of my shaft before offering her to drink? And not too regularly as to ensure she does not become subject to any sort of piss-dehydration.

On another head related note, what about Blowjobs? I mean if I'm putting my head and shaft into her mouth or expecting her to deepthroat wouldn't this expose her to the same bacteria? So should I alcohol swab my shaft before she bj's?

Maybe I only need to retain proper hygiene and shower daily, I mean what's the difference from her getting bacteria off my head in her mouth, in her throat, via my urine, or in her vagina? I generally don't expose my manhood to open air much so is it that likely I have something on my head that will hurt her? Perhaps I should shower when I get home from working prior to playing with her? maybe I should shower twice a day?
