Sir can I masturbate with DJ stent?

Hi.. Im 24 yr old male. i have an habit of masturbation. i think in my school 8th class i did masturbation first time. After a year it became a habit for me. i’m very much ashamed of having this habit. After doing masturbation, I hate myself that I cant control it. I think to control doing next time, but finally again I do it. From that time to till now I cant stop this habit. So more or less I masturbate twice a week anyway and in rare cases thrice a week. Accidentally during my college time I watched some programs in tv saying that masturbation causes not able to do sexual intercourse with partner. It causes not able to give a baby after marriage. After seeing that type of programs I got very much afraid of my life. Before two years I did laser eye surgery. Before surgery they did all pre-test for me. Then they said that your nerves are weak so we need to do two more extra test. After that extra test doctor said that we can do the surgery there’s nothing problem regarding the nerve weakness. I Think may be its family gene problem having nerve weakness. Maybe your grandfather too could had nerve weakness in his life. And now after two years of eye surgery I didn’t face any problems. As doctor said my nerves are weak in my body from my small age.After masturbating all these days I feel my nerves got more weak than before. I don’t know whether it is due to masturbation.But nowadays after masturbation I get head pain back side sometimes and not everytime. Anyway I feel nerves are weak in my body.I’m afraid very much that I cant do sexual intercourse with my partner if I get married. I’m afraid that I cant make my wife pregnant after my marriage. Please help me can I make a baby with sexual intercourse after my marriage? Do I’ve to get any treatment regarding sexual or regarding my nerve weakness or do I’ve to check whether can I make a baby with good sexual intercourse??

I am having a lump of width 1.5-2 cm attached to my left testicle at the upper part of the testicle since 10//11 years. (I have mentioned the width only because the shape of lump is just like a small testicle and I am unable to hold it from its length because it slips from my hand and some cord(perhaps epididymis) is obstructing me to hold it from it's length. most likely It's length is about 2.5 cm and I mentioned the width only). It is not causing any pain or problem with me. I put a torch light behind it and saw that it is allowing light to pass through . I masturbate much. Can this be cancer or is there any chance that I will have cancer in future ? I am scared of cancer Please help me. Can cancer be there with me for such a long period ? Is the light passing test is reliable or it is very very necessary to do ultrasound ?

Hi, I am masturbating last 10years. I masturbate twice or thrice a week. Now i feel some problems in my body. I do wanna know is it because of masturbation. My hands shake when i take a tea cup from a plate. My hands shake when i write. I have something like disturbance or a pain inside and above my neck backside when i concentrate and read some books or read something on a tv. (when pain occurs heavy above my neck backside i have aceclofenac and paracetamol tablets to reduce heavy pain but still i feel that disturbance there).I feel its because of nerves. I'm about to marry in a year or two. I'm very afraid this ruins my life or i cant have sexual intercourse with my partner. I'm very much afraid that all these symptoms happens because i masturbate heavy. Pls guide me..
