pea size lump

im a lot younger than all of these people on here, im only 14 and and worried as i have found a lump. im not sure where because i dont know what everything is called! im not too worried just curious. its not an ingrown hair because its my first time shaving there today and thats whe i noticed it. its a bit smaller than a pea but it is white in the middle. i believe its a cyst however i cannot bathe multiple times a day due to school starting in a couple days. please tell me what i can do? xxx
