MY wife and i has been together fo the pasted 21 years and this is a first for me to hear this. My wife told me that she feels nothing during a sexual intercourse time during her menstrual cycle. Remind you that we had sex within the 3-4 days after her cycle started. Normally, my wife can be stimulated/oral or penetrated and feels pleasure either way. Why suddenly she feels nothing. She noted to me that this is in one of those reare cases that we have intercouse in the early stage of her menstrual cycle. She mentionned also that maybe her uterus walls are thinker and she feels blotted and this would be one reason. Or, it's really me.???? I rarely ask these kind of question, now i am doubting myself. Is it me.....This issue never came up in all of the 21 years or this is like winning the million and i hit the 2 days of her life that she would be not feeling a thing.
