I am 40 and my husband is 53. He does not show much interest in having sex. I thought he was losing the interest because he was getting older but I recently walked in on him masterbating.twice. I have since discovered he does it almost every day but needs to watch porn to do it. Is it normal to have the urge to masterbate. But not have an interest in sex? It does make me feed bad, unattractive. And he's like a child if we talk about sex and years ago I asked him if he master bates and he refused to answer me. He's so awkward and it's not like he's inexperienced with sex. And words if advice? ( I don't like to take the lead with sex, I'm in control of so much in life I like to let go and I have told him this but he does nothing exciting).
My wife is the same as you but I'm 60 and still feel turned on. She does not mind that I watch porn and masturbate on a daily basis.
Sometimes she will watch with me knowing that it turns me on. I suggest you tell your husband that you don't have a problem with porn and some times watch with him even if your not to keen. I promise you it will turn him on and you will be pleased that he is pleased .
Let me know how you get on . Good luck !
