I have always found it offensive or a sign my sperm tastes bad if someone would spit. Fortunately almost never happens. I think it is one of the greatest turn ons for women in a relationship. Though I don’t smoke, drink alcohol, or coffee and eat mainly fish veggies and fruits.
Btw has anyone encountered a gal who likes to swallow your piss? (golden showers). I found one and it was very odd at first, then I realized the erotic part of it buuuut, then I realized she has done it with other guys too. I was sure someone made her and asked, turns out it was solely her idea.
