So I'm 16 and I like to explore a lot sexually with myself, I'm still a virgin in the sense that I've never had sex with another person. The other day I was wiping after peeing, and I noticed there was a spot on my vagina that was a little painful. Upon inspection it was a small bump by my urethra, and it was hard and painful to the touch. I like to think I take good care of myself when it comes to down there, but I'm afraid it might by something serious and I'm scared to tell my mom. Any idea what it could be?
