I am 66 years young and I enjoy masturbating a few times a week, or more, without an iota of guilt or any other negative thoughts about it. I am not going to stop until my parts stop working all together. During the scare for about 4 months about the likelihood of early prostate cancer starting with elevated PSA in May, I did some digging for information. Recent ejaculation causes our PSA to rise. I did not know that. I recall doing just that a FEW times the day before my annual exam and labs. My elevated PAS started a whole big mess and scare. Still not stopping; just being educated and mindful. After months of the standard testing (few digitals, more PSAs, MRI and biopsy) and waiting, it turns out I do not have cancer, nor do I have an enlarged prostate. I guess I have a "suspicious spot" there that cannot be explained, except that my urologist compared it to a freckle or skin tag - some ppl have them, some do not. Yay. As to masturbating, I noticed a significant reduction in the related fluids connected with male sexual activity over the years, especially when I reached 60. No changes in libido, arousal or great feelings with ejaculation at all, though. One thing I definitely will not do, and ask you to seriously think about it, is add any supplements to my diet that reportedly enhance the production of semen or libido. Some of those very add-ons will also increase the likelihood of prostate cancer! Be careful! I stay fit with a variety of exercises and very intentional healthy food choices. I think that is the key to enjoying life, including an active sex like (masturbating, included!).
