Recently, as in about the last week, i have been getting this pain. It only lasts for a short while but makes it difficult to sit down or walk, usually when i get it i just stand still or lay down until it goes. I have sex daily. Someone suggested that, because i do lots of martial arts and excersise, my testicles may be bouncing too much and this is causing pain. I never wear underwear but i should not think that has anything to do with it, i have been doing martial arts for 11 years and not wearing underwear for 3 years. I am 18. I was kicked in the groin a few times quite hard last week, maybe that is relevant, but i have been kicked here very hard in the past and has never affected me.
I am sure it is nothing major, but i would still like to know what might cause it.
