My husband has lost interest in sex. He says it’s not me, but his low libido. We are 63. He is on many meds for high blood pressure and heart disease, but can still perform. Do these drugs cause low libido? Also, he has prostate problems. He still hugs me, gives me flowers, and cards, but can a marriage survive without sex? He ls not a cuddler, never has been. After 40 years together, is there hope ? He says it’s not me, but he never forgets if I hurt him. ls he doing this for revenge? Should l just be patient?
