marry a woman who wouldn't swallow your load once in awhile?  Maybe that explains why I was never compelled to cheat or hobby on my late wife.  I didn't start this until after she passed nine years ago.

when I was in the fourth grade.

I decided I wanted in on it as soon as I could.  Then I did, and haven't looked back

And the answer is simple:  I'm a shallow pig who likes variety and hates commitment.
See, I told you it was simple.

1. I don't have the time or energy for a full time committed relationship...

2. Most women are not looking for casual...

3. I like to sleep alone...

While I've been in a committed (well, "committed" other than the obvious!) relationship for over a decade, I'm a big believer in the adage of variety being the spice of life.  I tried a full-blown affair but it got too tricky, too many emotions on both sides of the equation and nearly getting caught on a few occasions.  I figured I'd try this instead, no commitments or strong emotions and no phone calls or text messages to be worried about.  Instead, I just set up a "date" whenever I feel the urge and move on with my day.

get along best when they are both naked and intent on sexual gratification/satisfaction.  That was true during my 20 years of a not unhappy marriage in which the sex was better than most, it seems.  
 
But once I became single again, I wanted sex but wasn't interested in dating women my own age.  So I took my chances with an escort at least half my age.  Got very lucky on my first encounter -- a 22 year old cuteheart nympho with a body out of a magazine  -- and I was hooked.    
 
Having NSA sex with young hotties on my schedule is a no-brainer for me -- I prefer young and sexxxy, variety, NSA and a sure thing to the maybes and vagaries of a dating situation.  The hobby gives me all of that.    
 
Life has always been good but it's never been better b/c hobbying is by far the best option for me.
