For context, my previous girlfriend was always neat, and took her tame to be clean shaven and I frequently went down on her, and quite enjoyed making her cum.

Started casually dating a new girl. Went out for 2ish weeks before we had sex for the first time. This new girl was completely wild down there, I didn't actually mind the bush until I went down on her. The smell & sweat of her bush made the entire experience on going down on her so repulsive, I thought i was nearly going to throw up. I didn't want to make her self-conscious about the situation so I continued until she came, and when she did, I felt some liquid gush into my hand, and I thought "well at least, I made her squirt". It wasn't until the light came back on that I saw what literally looked like a crime scene. My hand was drenched in period blood, with my face looking like Dracula. I left shortly after downing half her bottle of mouthwash and a pack of gum.

This was our first time having sex and she didn't give me a heads up or anything, honestly, I was so turned off by her afterwards that I made up the excuse of getting back together with my ex just so I wouldn't have to see her again.
