i noticed this thing recently my balls relax and contaract all the time even when am doin normal things,think of a nice place it happens,think of normal things even then i get the feeling in my balls

also i have noticed i get really turned on very quickly these days the slightest contact with a girl can trigger it and i wasnt like that 6 months ago
also this is playing around with my head as am getting anxious,because my convultions happen so regulerly,when i think about my girlfriend or even my mum,sisters,brothers,friends etc i get the contractions,that shouldnt happen. i thought that was asociated with sex not for example when am looking foward to something ??

can anyone help me cos its starting to bother me
