Sexsomnia

Does anyone else's SO have sexsomnia? I didn't know it was a real thing until I started doing research on it. After my now husband and I had been together about 6 months, I started to notice he would occasionally fondle me while sleeping. There have been times he'd be snoring while putting his hands down my pants. After the first couple of times I confronted him. He was embarrassed and had no idea that he had done it. It doesn't happen every night; I'd say maybe 3-5 times a month. Tonight was the first night he has grabbed my hand and shoved it down his pants. I pulled away and he did it again. He isn't actually wanting sex. For one, we just had sex and 2, he's snoring. Anyone else deal with this? Is there something that triggers it more for your SO? And how do you go about the situation?
