Really don't mean to go in circles here.
Sparkles said she really hasn't felt any libido for a number of years.
We can rule out birth control meds (she was not on them since we've been together), medication of any kind (she doesn't take anything), depression (she isn't depressed), exercise (she exercises every day for an hour), health problems (very healthy, thank goodness), ummm....what else? Stress and anxiety? Nope.
