My(35M) wife(36F) has lost her interest in me. What can I do to get her attention?

Hello. I(35M) have been married to my wife (36F) for 4 years, together for 5. We 2 are both Asian and I feel that it is important to mention because I believe it may play into the situation that is occurring now in our marriage. We did meet on a dating app, which was an adjustment for both of us. After matching, we used a dating app to video call each other. When we did meet for the first time, it was like we were long lost friends who had finally reunited. <br><br>She was very attractive and had a very nice personality. We had a great time on our first date. Later that week, we had our second date, which was also very good. Following that week, we had a third date and then she stayed over at my place. After that, she moved in with me and we were living together before we officialy became boyfriend and girlfriend. A few more months passed and then we got married. It was a very quick courting period, but I had never been so smitten over a woman in my life.<br><br>The first 4-5 years of our relationship were incredible. A couple of months back, I began to notice a change in how she interacted with me. She wasn't as flirtatious with me and I couldn't sense that she was interested in having sex. At first, I wanted to give her some space to see if that would help improve things, but she hasn't really initiated any form of physical intimacy or even sit next to me on the couch. <br><br>I've become so confused and I don't know how to approach her. I don't know if it's a hormonal imbalance or if something else is going on that I am not aware of. I feel that trying to initiate a conversation about her libido is going naively, so I need advice on how I can approach this issue without her feeling uncomfortable.<br><br>Thank you.<br><br>TLDR!: My wife and I have been married for 4 years, and for the last couple of months, she seems completely out of interest in me. I don't know what to do.<br><br>Edit for update: Hello. All of you have helped me identify what the issue was and how I should proceed. Here is what happened.<br><br>Last night, after work, I stopped by a pharmacy and picked up some of the supplements that you all suggested. I also bought some flowers, which are her favorite.<br><br>When I got home, I had her favorite food cooking, and then I began to read a card that I had prepared for her. I told her that I loved her very, very much and that she means the world to me. I told her how much I appreciated everything that she does in our life and asked if we could go to the pharmacy together. I showed her the supplements and explained what they did and how they could improve our sex life. <br><br>I told her that I believed that she was an amazing woman and that I wanted to make sure that she felt good and was satisfied. Once we were at the pharmacy, I found the flower that she likes the most, and I told her that I was going to get her those flowers every week because I wanted her to feel special and appreciated.<br><br>After that, we went to bed, and I was glad to see that she seemed happy and appreciated what I had done. She said "thank you" and that she really appreciated what I did for her, and she said that she loves me very, very much.<br><br>I'm very happy, and I think that the feedback you all gave me really helped me make this moment special for her. Thank you all very much.
