I’m 16 years old and over the past few days have been experiencing stinging sensations on the outside of my vagina, I am currently on my period so I’m unsure if that could be the case (although I’ve never had it like this before) I’m honestly too scared to get a scanning and I definitely wouldn’t tell my parents. Me and my boyfriend have been together around six months and have intercourse regularly although he always wears protection, however I noticed it was quite painful the last time we did tried it. I’ve also noticed excessive “chunks” coming out in my blood which have a weird skin like texture, I’m extremely worried and want to know if it could be an sti. I’ve even looked at my vagina myself to see if I could see any weird symptoms but it just looks a little grazed. It doesn’t hurt when I urinate but when I wipe it often stings.
