Can masturbating alot cause a slight pain in left testicle and lower left in belly? ?

It is certainly possible that could be the cause , Your testicles can get tender if you have several orgasms over a short period .However if you have pain and are worried , best get the doctor to check you out . Reduce the frequency of masturation over a few days and if there is still discomfort then see your doctor

nope, that 's another problem

It's normal just relax. Have a beer.

sounds like a inguinal hernia, just don't pull  your penis too hard and too vigorously. easy does it.  enjoy the pleasure. don't be silent. scream out your moan. if you repair the hernia do not go for the mesh , do it open method.

No, unless you were banging your wrist into those areas it shouldn't.

Its a hernia - I have one too

u won't know till u stop for a while. Your penis is not a toy.

Sounds like you are describing a Hernia.

Sounds like it does for you!

No.
