Dear Samuel,
It is difficult to comment on this mass because I don’t have the opportunity to examine you. There are several structures and potential abnormalities that can account for the description you gave. These are namely a spermatocele, hydrorocele, recurrent varicocele, or hernia. All of these can be better characterized on physical exam. If there is any question, an ultrasound can be obtained to determine if the mass is intratesticular or extratesticular. There is a big difference if the mass is coming or growing inside the testicle or from the surrounding structures. Most likely you have a spermatocele or a hydrocele which I will discuss in detail. I don’t think either is related to masturbation. There should be not internal consequences to excessive masturbation. I have heard of skin problems due to certain lubricants.
A spermatocele is a cystic structure or outpouching of the epididymus. The cyst itself is usually firm and nontender. It is usually filled with sperm and epididymal fluid and considered a benign lesion. It is possible for it to lead to a decrease in fertility however this is uncommon. The most important part of diagnosis is to make sure there is no cancerous lesion. Again this can be done by a good physical exam or ultrasound.
A hydrocele is a collection of fluid around the testis inside of the tunica vaginalis. It is usually benign, but sometimes it can be a malignant process. Again, an ultrasound would clear this question.
I can’t tell you if this is a cancerous lesion over the internet. If you have a lump in your scrotum you need to be examined by a physician who can decide if you need an ultrasound.
