Should I be worried?

Sorry in advance for my lack of knowledge in regards to my own body, but I grew up in a rather reserved household so I am still learning. Basically, my boyfriend fingered me and upon finishing we saw that there was a hair that was on his finger that was still a bit in my vagina. Having long hair, this seemed normal so I pulled it out, but I'm still a little worried there's a possibility of there being another hair inside my vagina that didn't come out. I even started to "feel" something down there, but that just might be in my head. Plus, for the first few hours I didn't as the thought of the hair being inside wasn't in my head. I know this sounds all bizarre, but I get really worried in regards to body/health so I just want to know if there should be anything to worry about? And some education on the vaginal canal would definitely help. Thanks in advance
