It shows it was never something you wanted with him in the first place. In the modern age, however, we men have witnessed that most women do experience plenty of sexual attraction and arousal, but usually only for the top 10% of men with status and plenty of muscle. Women claim often to have a low libido, when what they really mean is that their partner simply isn’t sexy or new enough for them.
Unlike other commenters here, I believe that all men should absolutely get a prenup and be ready to leave when their wife gets bored of them. People are ready to show so much love and support to women when it comes to every little issue these days while the needs of men are ridiculed. If any woman starts to see her man’s healthy desire for sex with her as something akin to a dog humping her leg: she’s lost all attraction and respect for him. She does not, in fact, love him anymore and should end it for both their sakes. She was most likely never attracted to him or his body in the first place anyway.
Jane, I think a lot, if not all, of what you said is spot on. I think the bitterness comes out fully in your comments. I think what might be getting missed, is guys don’t realize the sexual fun and excitement is supposed to be short lived. We think this is who we are marrying. We think we are e page as we are sexually. Then after marriage that rug gets pulled out from under us and we are in a relationship with someone other than who we thought we married. I’d say we basically feel “tricked”. Your shopping analogy doesn’t work either. I enjoyed running everywhere with my wife and still did after we were married. It wasn’t until she changed the relationship that I didn’t want to do those things anymore. Apparently, “relationships change” is an adequate answer when it’s regarding areas SHE has changed in (less sexual) but doesn’t accept that as an answer to why I no longer want to do certain things. I even explained, “you can’t change our relationship and not expect it to change me as well”. For the several years prior to our marriage and early on in our marriage, she was highly sexual and I couldn’t be around her enough. I loved going shopping with her. I loved watching her try 
on clothes. She always kept my attention because of the “spark” between us. Now that it’s not a spark, and more like a “comfy blanket” stage for her, I’m much less interested in doing those things. It’s not enjoyable any longer. Not because I’ve changed, but because she’s changed.

Someone give this man a star! I am a female, married to another female, who just was informed by my wife she feels being sexual with me is more of a chore because she no longer holds a sex drive… She states “It’s nothing you did, my body is just tired.” She states once she can figure out the balance between work and marriage “hopefully that changes.” Okay but what about all those moments when I wasn’t in the mood because I just pulled 5 straight 12s and literally can’t figure out how to hold my head up let alone be sexual, but then I was informed I was no longer making us a priority?

I just happened across this site and have been reading the comments. I swear it sounds like I’m listening to myself. Every comment depicting a woman with a changed and negative attitude towards sex is my wife. Sadly, I’m pretty sure she took this desire to be desirable by other men (as addressed in the to the extreme and had an ongoing or multiple affairs. I have decided for the sake of my children to wait until they’re all out of the house to confront her. Did I catch her in the act? No, but a husband knows. Besides the betrayal, what has gotten under my skin is her thinking she has gotten away with something. Sadly, she will probably spend the second half of her life alone.
