My wife finally experienced orgasm with the help of a vibrator after many years of marriage. For the first couple of years, she described the feeling as a wave tingly pleasure that would start from her clitoris and shoot up to her ears followed by many very shallow but pleasant contractions around the surface of her vulva. Now after several years, she has a completely different feeling. No longer is there an electrical whoosh feeling. She now has much deeper and stronger contractions but fewer when the orgasm “catches” as she puts it. I know this because I can feel and count them with my finger or tongue. Overall it seems to take her a bit longer to come than before. Was was 15-20 min, now takes like 30 mins in average. Overall she misses her previous pattern and wonders if it will ever come back. Is this change a normal thing that females go through over the years? Or is this a permanent change? There really is no change in her overall health while her orgasm style has been evolving.
