I don’t enjoy sex with wife

As the title states, for the last year or so, I really haven’t had the desire to have sex with my wife (we’re both 34 years old). We’ve been married for five years.

I feel awful saying this. She’s a great mother to our two children and she’s a pretty woman (she’s a yoga and fitness instructor). She’s fit, motivated and I do love her. This isn’t an attraction issue at all.

There’s been no infidelity. I never turn down her advances and we do have sex. That’s not the issue. I simply don’t enjoy it anymore. It makes me feel terrible for feeling this way; like I’m a bad human being.

I’m not looking for any advice on how to improve this. I have a general idea of what I need to do. And I have been more vocal about it to my wife. But I need to walk a fine-line. I don’t want to cause other issues in our marriage. We live a good life, with healthy and beautiful children. I don’t want to mess that all up due to this issue.

Although I’m not looking for advice what I am looking for is to hear from anyone on if they’ve ever felt this or are currently feeling this way. I suspect it may only be a guy thing/issue.

I’d appreciate any feedback and to hear what your situation is like. Thank you.
