My wife and I have been married for 25 years, up until about 6 months ago, sex was maybe 2 times in a month. Since then it has grown to a consistent 2 or 3 times a day with the initiator being my wife. What has also started occuring is her orgasm. until 2 weeks ago, she had never experienced one before this. Over the last 2 weeks she has finally become interested in toys and understands why everyone masterbates. My worry, is that there might be an underlying cause to this rapid and drastic change (though don't get me wrong, I am loving it). She is 44 years old, overweight with HBP and 3 major spine surgeries, I am 46 and could stand to loose about 30 lbs and work from home (which is not helping the situation right now, lol). Usually about this time peoples libido travels in the opposite direction. Should I be worried?
