is this blue balls? we were dancing, but erotically

is this blue balls?

while i was in party i was dancing with a couple of girls and the things its not your normals dance its a girl basically putting her bum around penis area which is the popular jamaican dancehall dance , there was one specific i was doing it with and she seemed to have a very big bottom so when she was doing it really aroused me. after a while i realised my lower back started to stiffened  up  and achd and leg started to ache to be honest felt like whole body went stiff and was aching  my balls werent really hurting but felt uncomfortable that i had to hold it but i felt some relief when i went to the toilet and peed 

i dont whether it is blue balls because everytime i see blue balls.they talk how they get pain in their balls for me it wasnt really that it was  the fact my body stiffened up and started to.ache

Btw im 16 year.old boy who is a virign and this is has happened to me twice
