Vagina discharge? Guys: “its gross”

Why are guys grossed out by it? Im talking to two guys and one of them is grossed out by it and so i asked the other one if he knew what it was and showed him a pic off of google (ill tag what i sent lol) he said “yeah thats a runny nose lol” “that white stuff ain’t good”. Why do guys think its gross? Why are they so uneducated? I personally thought that discharge was just good bacteria cleaning your vagina? And natural lubricant? (If it doesnt smell itch or burn down there) Whats up with this how should i go about this with them lol One is 31 and the other is 23 if that makes a difference because ik alot has to do with age and experience but damn they grown men and should know this🤦🏾‍♀️💀
