I guess the best way to phrase it...
My lust drive went away with maturity. My sex drive is still there but reformed.
To sit and just cuddle can be as much a turn on as a wild night would have been in the past. At 51 ..everything still works vs at 21 when it worked even if I didn't want it to *LOL*
Not a decrease in sex drive but a refocus of energies and desires is how I see it.
