Help vagina problems

i have not been sexual active i have only kissed one guy, he put is hands down my pants adn grabbed my back side and thats it.

That was a month ago, recently i have a lump inside my vagina the next day it had a white head and by the end of the night it poped and bleed and went away.

I started thinking it was somthig serious and made my self sik thinking about it, from that i got three olsores inj my mouth that hurt everytime i started stressing.
2 days ago i had tingling so i masterbated and it went away but i noticed that my skin on my bikini line and some areas on my lips where pealing. I also have clear and white discharge and it smells like cheese or something old.

There are no lumps besides the small lump that allgirls have on there layers. Im close togetting my period and my back started hurting today.

Wat is it ?
