<s>[INST] I am 65 years old and my sperm has turned watery and decreased in volume, sometimes hardly any at all. The sensation has decreased to sometimes there is no pleasure at all. I am single and haven t had sex in about 4 years. I very seldom masturbate because to be quite honest it is very seldom pleasurable. Before this problem arose I had a very high libido as in wanting sex everyday and more than once a day and I was still in my upper 50 s. The pleasure at that time was so strong I usually had to scream out with the feeling. Is this problem anything to worry about? [/INST] Thanks for asking in healthcaremagic forumIn Short: you cannot be like before(young) alwaysExplanation: It is very normal to have decreased libido and performance after 50 and above years age. As you get older your frequency of sex/masturbation decreases and this is entirely normal and normal ageing phenomenon.                  You can consult your doctor for viagra prescription for getting good erections after thorough checkup for cardiovascular system. Hope this will help you. Good luck. </s>
