Female led relationships discussion

I need some advice on lubricant. I’m getting plugged and my little cock will be locked for an event tonight. This is the longest I’ve ever kept a plug of this size in place; usually, it’s only about half an hour at most. Does anyone have recommendations for a lube that stays effective internally for such a duration so removal isn’t too painful? Silicone seems like a good choice, but perhaps something oil-based might be better. Thanks
