Wow, this thread sure seems to have evolved. =)
Anyway, as a former carnivore turned veggie i can safely state that my cum has changed a lot since i stopped loving the cow.
From being something I´d rather not smell or taste or have anyone i truly cared about smell or taste, it is now, changed. in the words of a long time partner my cum has gone from toxic waste to dessert. It's actually sweet! (We believe in sharing, especially if there's more than two people involved, go figure.)
I lived vegan for about a year, and it didn't add or lessen the effect in any way.
Back to being a vegetarian who enjoys diary products now. Seems that eating loads of meat was the main culprit.
Amongst other changes, my entire digestive system actually *works* as intended now. I live after a very full schedule, 40 - 60 hour work week, mountain climbing at least three times a week and trying to have a life. Gets hectic.
Three years ago i had the start of what my doctor described as "if it was about half the size it is, it'd be an ulcer, this falls more under the heading of gaping intestinal wound"
I was told to take a long vacation and start eating a LOT of medication.
I stopped eating meat and went full on veggie instead, had the WORST four weeks of my life and than woke up one morning and just felt, i dunno, not in pain at first and then better by the day. Haven't looked back since. Tried going vegan for a while but i travel a lot so it's a hassle and I love cheese, milk and eggs to much.
So, benefits, for me, some huge in terms of health, and some nice in term of better sex.
