HELP ME!!! WART-ZIT PURPLE AND ANNOYING!!!!

I have a huge swollen-ish type zit or wart on my inner thigh close to the vagina but not touching it.
Its purple and smooth but its swollen and comes outward,
I AM NOT sexually active, I find it quite embarrassing to speak to my parents or a doctor about this, i just want a at-home treatment i can do myself, i have tried to pop it but only blood comes out, which doesn't make the swelling go down, its at least an inch across, and its very annoying because I'm planning on having sex soon and i don't want the guy to be like "What the **** is that?!"
But i want it gone as soon as possible, what should i do?
