This is exactly what I've been saying on other similar threads.
I've had a set of dilators now for about six weeks, and they've made a big difference already. I'm a lot more relaxed and confident when bottoming, especially when he's bigger than average.

These are the three larger ones in a set of five, that I try and use regularly.
I tend to leave them in for 20-30 minutes which is usually enough. Any longer and they start to dry out, which can lead to some pain when removing. Unlike butt plugs, they don't stay in when walking around, so you need to devote some time just lying down.
But I think they are much more effective.
