Edging closer to my 4 series, it is apparent that my body is changing. But 1 thing boggles me, and not too sure what it is.

Being a man, I enjoy looking at ladies. But unlike when I was much much younger, I don't seem to be able to get instant hard-on? It used to jump at the slightest trigger - a whiff of perfume would have drive  me crazy!

I am married, and leading a quite sedentary life- desk job, 9to5, and by the time I reachef home, I'm spent. Sex frequency has dropped with wife, being married for years. But I do Masturbate and watch pr0n every once in a while, out of urges - and boredom of daily life.

Not sure if it's to do with lesser sex drive, or signs of erectile dysfunction?
