Age & Sex

I was on the line with my banker friend and he told me that sex urge is getting less with age. It is like the heart wants but the body cannot do it. Yes, it is a fact that young married couples do it everyday in the first year, every alternate days in their later years, once in a wwek and degenerate into twice a month and then once amonth, once in two months and on and on until once in a blue moon. My friend was karate black belt exponent and he exercise frequently in the past and now ends with a pot belly and cannot do the flying kick anymore. This is the degeneration of the body and the mind. It is natural and gradual and we do not have to be shy about it. Finally, we need os medicine or drugs to life up us up to do the sex job but it is a personal choice. There is no compulsion on this decision. If you feel like it and cannot do it, just boost it up by a drug or medication. So , I wonder how to keep up our healthy body. Do we need sex to remain healthy and passionate ? Do a prolong sexless life hurt our healthy or make us more insensitive ? What about the monks ? They abstain from sex and does they release themselves once a while ? Is sex a necessary thing in life or for our healthy. There is a finding that regular sex makes us more relax and we feel better but no sex also give us the same feeling after some physical exercise or yoga or meditation. So the really need of sex is all mental or our mindset ? Then why do we have an organ which is so sensitive to touch or penetration ? Is sex is only for birth makeing ? The more we make love, the more chances of getting pregnant and is it the real reason ? So,if we don't want children that the organ become useless ? Can we use it for enjoyment instead of child making purpose. WHy so people are so frigid and some wants heavy sex ? It becomes a personal preference. Does a man or women without sex die faster or live longer ? There is fact and findings to support but again, it is personal. After living all these years, it is still a puzzle to me what is the purpose of sex. Some people needs it more , some less and some do need it at all. Just a passing thought. Namaste.
