Everything was perfectly fine. My erections were always hard and long-lasting. Sex life was perfect . But since last 3 weeks my erections have not been long lasting also it has become very hard to attain erection before sex. The only time I'm hard is when I wake up ( morning wood) rest even if I attain it stays for a very short span . Please help me as it is affecting my confidence. Is Shilajit a solution to this. Or maybe some kind of exercise or therapy. Please advice .
