As title asks, do you think your appetite or hunger affects the sessions at all?? Maybe if you are full and have a fuller stomach would that affect the pressures of the toy?
If you are going on a date where sex is inevitable, bang before dinner. A full belly is detrimental to a good time. Hunger can inhibit the pleasure also, so I have to find the happy medium. Early morning hours are great for sessions, but those sessions have two enemies for me: hunger and needing to get out of bed to nature's call. All about finding that happy medium for me.
Maybe not appetite, but eating and being full. My best sessions are all between 11am-3pm. I eat decent breakfasts that can hold me off until later afternoon for late lunch. If I'm going to have a session say around 1pm, I'll eat some eggs and toast or something like that around 10am. If I plan for 11am-noon for the start of my session then its same breakfast around 8-9am. If session is mid afternoon then I'll eat breakfast early by 9am, cereal or something like it, and then eggs and toast/grits or soup or something for lunch before 1pm. I've tried sessions at night in the last 5 or so years and even if its a light dinner, I'm just not getting as much out of the session.
