Transferring of the Impurity

I once had pre-ejaculation on my hand, and I did not wash it. However I went ahead and I sat and touched everywhere on the carpet. With this being said, I don’t know if the impurity transferred or not because, my hand wasn’t neither wet or dry. It was more to like a moist matter. HOWEVER my hand was 100% not wet to a point where if I touch the carpet or a think peice of cloth it will soak it. Due to this; I now feel there is impurity on my carpet, and I cannot make wudu because I keep thinking if I step on the impurity with wet/moist feet, it will transfer to me and I when I step on my wudu mat then this will become impure aswell because my feet were wet. Can someone please give me some insights on this? Jazak Allahu Khairan
