Dilating anyone help

My ob gave me the go ahead to start trying to find ways to dilate, I know that doesn't mean he's coming but she said it will make labor faster. Anyways, I'm single so I can't have sex, I've been taking evening primrose oil and I was just wondering if anyone else had an success stories with anything else or had any recommendations. It's also like 12 degrees where I live so walking sounds no fun but I might just try anyways. Thanks 🙂
