Why does sex hurt me and feel strange?

maybe youre not COMPLETLY comfortable having sex yet. so u wont get as wet(which is needed). its also possible tht u jus cud not b ready for sex. nd the eletric shock u talkn about happened to me when i mastrubated b4. u shud jus not have sex for a while. im talking 2weeks. the vagina can get over stimulated....do u feel completely comfortable having sex?
