I couldn't imagine myself having sex with a man I'm not attracted by at 5am (I've always hated morning sex even in my personal life as I'm not a morning person at all) You guys are very strong minded !
The earliest booking I've ever done was 8am (first and last time I did that). I usually never tend to take any booking before 10am or 11am (I very rarely get early bookings enquiries anyway).
This is the biggest reason I hate overnight bookings. I can't bear being touched up and then having sex first thing.
I have now changed my overnight schedule to wake up in the middle of the night for round 2 (if absolutely necessary) so I can leave ASAP at first light, without needing to wake them hopefully
Away from overnights, I am a morning person and often hit the motorway by 7.30am to beat some of the traffic for my outcalls.
As others have said, I always need full fee or a chunky deposit in advance if they book the night, before, but that's more to prevent them changing their mind overnight
