Your cock is designed for a life time of fun, but unlike a sex toy, you can’t get a new one if you but it or wear it out. You knew this, but did you know that there are certain jerk-off positions where it is possible to cause damage without initially being aware of it? For example, aggressive thrusting face down against a sheet, pillow, or even a carpeted floor can injure the urethra in such a way that urine exits the cock not in a stream but in a hard-to-control spray.
Urethral trauma can be so severe that you may no longer be able to use a urinal and will have to urinate while seated.
In extreme cases, masturbation or sex with a partner can even cause a penile fracture. This painful condition is when an erect penis strikes a hard object or is forced downward. It’s a medical emergency which often necessitates surgery.
There have also been instances where guys have thought it would be clever to experiment using glass vases or even glass champagne flutes. Delicate glass and your cock thrusting in and out of it is definitely not a good idea.
True story, one guy tried jerking off using a glass vase gripped by the lid of a heavy trunk t hold it in place. He managed to smash the vase on top of his cock and very nearly sliced it off!
Another guy thought it would be awesome to jerk off into a warm apple pie. He placed it in the microwave for a couple of minutes and second degree burned his cock when he plunged it into the pie.
Think carefully before you plunge your cock into any inanimate object.
Here’s something else to be aware of; if you frequently stimulate yourself in ways that does not simulate sex with a partner, for example, stroking very rapidly or with great pressure or friction you can develop retarded ejaculation. That’s a type of sexual dysfunction in which it is difficult or even impossible to climax during partnered sex.
