Your body has billions of billions of electrons and protons in it. why don’t we all repel or stick to each other?

We do not feel the gravitational forces between ourselves and the objects around us because these forces are extremely small. Electrical forces, in comparison, are huge. Since we and the objects around us are composed of charged particles, why don't we usually feel electrical forces? 
The charged particles of which we are composed are balanced: each positive charge is balanced by a negative charge, so that overall we are electrically neutral. Any imbalance in electrical charge is quickly rectified by picking up charge from something else; that's the reason that we get little shocks in dry weather or in the winter.When combing your hair, you scuff electrons from your hair onto the comb. Is your hair then positively or negatively charged? How about the comb? 
The hair loses (negatively-charged) electrons; the comb gains them. Therefore your hair becomes positively charged and the comb becomes negatively charged.Hope this help,tried to give an example and some questions so u can understand it a little more.

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o
