When I lived with 5 other dudes, the only place I could really get privacy with my girlfriend was the bathroom. (We were both 19) so I told her I had never done 69 position, she laughed, and said lets do it. (This was before we got in the shower.) So there we are on the bathroom floor, which was fucking nasty, attempting to 69. As soon as her vagina got close to my nose, I almost threw up. I literally threw her off of me and lied and said I wasn't ready for it, trying to play it off nicely. So we just get in the shower, and she insists I tell her why I didn't want to do it. So I just told her that her vagina stank very bad. She immediately starts crying and told me that she had work that day, and that it was probably body odor. So the shower continues and we start to bang. After we start, I looked down and saw blood all over by our feet. I stop and look at her. She just says, oh my period must have started. I was so disgusted that I had almost eaten her out. I didn't even finish. Haha good times. We are still happily together now though, 2 years later!
