Re: distance varies with excitement level.
In a nutshell, both you and I are finding diminishing sex drives to be the reality of ageing.
That said, we are both approaching it in different ways. You are accepting of the situation and prepared to v1agra your way to explosive sex - thats fine, it works for you.
My approach is a lot more complex - I am trying to undderstand my sexuality in much more depth - understand my triggers and explore new avenues - combine this with an holistic approach, I am considering stress, relationships, work, environment, toxins, detox methods - in fact, you name it, I am considering it! My belief is that men in their 40's and 50' and 60's have the ability to have great sex without drugs - somehow the world we live in is more dangerous to men now - that is why world wide there have been huge declines in the quality of male sperm these past 30 years - central heating, manmade fibres, drugs, chemicals etc all kill sperm.
Men are sex driven hunter gatherers used to the cold and being very physical in what they do - now we slump behind a car steering wheel!
So, for me, I am trying to reestablish within a modern lifestyle sufficient eco for my mind and body to restore its sexual functions. Already I am seeing results. Yes, its slow, but with I unloaded in mmy wife the other night it felt better than it has for years. I am more "aware" of what I am doing and concentrating on light sensations rather than the more rougher aspects once enjoyed.
Chemicals are not for me, certainly not v1agra. I do not blame you for using it - and if it works well for you thats ok - but I am so confident of my appraoch that I am sticking to it.
Up to 3 years ago i used to have 3-6 colds a year - now my immune system is so strong I rarely if ever get any infections at all - even when surrounded by others coughing away in a room!
My body is strengthening throguh the changes i am making - not just sex - if you like, i see declining sex drives as a symptom and not a cause - thats the difference.
Good luck. We are on different paths but share a mutual destination - improving our sex drives etc
