I'm struggling with my (m38) new marriage to my wife (f41). We've been married a year and my libido has dropped compared to when we were dating. We don't have any kids so idk if this is normal. I will get my testosterone checked but I've always considered myself a 1-2x per week guy. On average atm it's perhaps 2x per month and she said she isn't happy with my levels of intimacy and said she doesn't want to initiate with me as she is likely to feel rejected if I'm not in the mood. I love my partner and when I'm in the mood for sex she's so sexy to me. I think part of the reason I'm not always attracted to my partner is that she has bad breath in the mornings and also sometimes goes days without showering. I brought up the body odour before and she went super cold on me even though I tried to say it gently she said I was rude and I should do it more light hearted. Next time I joked about it and she still flipped out. We realised it wasn't the delivery but her embarrassment about it. She said I'm not allowed to talk about it to her so I said fine. But sometimes if we get close in the mornings in bed my body and reactions can't lie unfortunately and I'll turn my head or something and I'm very very sensitive to smells and other sensory things so it's really not a turn on if someone smells bad to me. I tried to bring this up again yesterday and she was angry and said 'so it's al my fault then?' and has ignored me since. I tried to reassure her that I love her and do find her attractive but I have sensory sensitivities that I can't just turn off. I don't know how to tell her these things gently and I don't think I'm unreasonable to ask for some basic hygiene but maybe I'm in the wrong? Any advice would be great
