Hi there
I can speak from personal experience. It can be quite uncomfortable, an elephant in the room when one or both partners are unable to initiate intimacy/sex. safe to say that it does not mean either one is at fault or to blame.
Its tricky, truly when your turned, on, horny and want to have sex, but the woman/your wife shows no interest. The man becomes hurt ad may feel insulted, feeling consciously or subconsciouly there is something wrong with them etc.
From the womans percpective they will be feeling the same, even though they may not express it verbally and be open about how they feel or what they are thinking.
This is what I personally recommend.
Speak to her. Make a specific time, tell her you would like to set some time aside so you can talk Make dinner, light some candles, anything really so the atmosphere/environment does not come over as confrontational.
Then talk to her, ask her what she is feeling. I say this because feelings and the realm of the senses is crucial for a woman, more so than a man. I do not mean this as an insult, at all, Men are very physica and are not often open nor receptive to `bigger pictures` when it comes to feelings/emotions.
Both of you want to be honored and recpected, this can come about via openm honest and sincere communication. Hold he rhand look into her eyes, sit with her on the sofa etc. Just let what ever happen, happen. There may be painm hurt confusion, frustration and anger on both sides, then there will be realizations, things you did not know, or just were not aware of.
Ask if there is anything, she wants/desires, anything she wishes to see changed. If she says `you ask for it all the time, ` OR `stop putting pressure on me` then try and understand what is behind that. When a woman says such things its because thats how they genuinely feel, could be linked to how she/women have been brought up to feel about sex and honoring/obeying their man or men in general.
Its going to be a gradual process, but in respectful open and compassionate communication, and when you do it frequently there will be growth on both sides, she will feel she can `approach` you and you will feel the same, without walls and defences coming up.
See how that goes first, then introduce the subject of what she would like in bed, or out side of it when it comes to intimacy/sex etc, and do not be frightened to come forward about your wishes/feelings.
About women not coming with their man:
I am one of these women, its not because there is something wrong with me, for the longet time I thought there was, but there was so much crap I was brought up with, and other things that I `held back` I did not know how to have a relationship with my body, my clit never mind with the guy I was with.
Its a very personal and even sacred journeywhen it comes ot orgasm and release, and I am not just talking about clitoral orgasms, but full body orgasms. Look into massage, aromatherapy, times out in nature/sun. Fun shits and giggles, sex needs to be about fun, and not ebout expectations ideals or presumptions.
If she is open about sex toys then offer to buy her one, if she is not then dont push her, lots of kissing, cuddling, time, maybe set one evening or day a week where its for you and her only. Phone goes off, kids (if you have any) go to their friends/baby sitter, just make sure you have `that` time on `that day` be it watching a film, going for a meal (inside or out) going for a walk in the country side, anything really, but something you and her like.
This is a lenghty post, but there is a lot of food for thought, but if you become disciplined in he above and meet each other half way (which you will if you follow some of what I have said above) then your sex life will improve, but not just your sex life, a lot of areas will improve, internally and externally.
