Little pea?

Genevieve • Sophomore//Swimming// Cheerleader// 14
I was taking a shower and like I do on a daily basis I was washing my anus area and oh did I feel something. It was like a little pea, or a tag. I'm not really sure..it's like my butthole, a space, than the little puffy pea that kinda hurts when I brush over it. And like I usually wear thongs cause they're undetected but it hurt. I'm wearing regular now, but it still gets between and you know the rest. Can anybody please tell me what this is? Thank you!
