Am i over masturbating? i am kinda worried, i dont really know, any help?

I am 20 years old, in good shape and i have an active lifestyle (leaving for army next month) and i touch myself sometimes about twice a day, or maybe 3 times a day, (but sometimes only once a day) and i have this pain in my pelvis, if you were to do a situp the muscles in the pelvis kinda hurt (sore) and my testicles arent really in pain, maybe very very miniscule if anything at all and i have some lower back pain, could this be from over masturbation? im worried and it doesnt hurt that bad but its a nuisance pain!
