I've been masturbating twice or even three times a day for quite a while now, and Im starting to notice some concerning effects. After walking or going up stairs, I sometimes feel briefly blind, and my bones ache as if I'm really weak, which seems odd since I'm only 19 and a half. Are there any medications or methods to help control this?

It sounds like you may be experiencing symptoms of fatigue and possibly overexertion. It's important to prioritize your overall health and well-being. To help with your symptoms, you can consider taking a multivitamin supplement to support your overall health and energy levels. Additionally, you may benefit from a supplement containing calcium and vitamin D to support bone health. It's also important to ensure you are staying hydrated, eating a balanced diet, and getting enough rest and sleep. If your symptoms persist or worsen, it's advisable to consult with a healthcare professional for further evaluation and guidance.
