as you note...be careful of medications..I have tried 4 different 'anti-depression' drugs, and all they did was make me thirsty and _flat.

That being said, there are variations in hormone levels in people as they age or for other reasons...and stress WILL create confusion about what is wanted/needed. The most impostant sexual organ is the brain, and it can be jaded, tired, distracted...etc....

What to DO? Well, I once worked in an 'adult book store', and met many folks who selectively used eroticia to stimulate lost creativity. (yes, that means 'porn', but I hate the negative connotations)

But the important thing is perhaps to get professional help, if the problem is ongoing and of long standing. So many little things could be adding up to one situation, and once a bad habit starts, the cycle gets out of hand.
