I find that after most sessions after seeing an SP, I tend to go for a meal.
It's normal to get hungry after, no? What's your go to snack/meal?
I tend to just google and see what seems good nearby. I tend to want ethnic like afghan (underrated) or jamaican jerk chicken. Maybe Wendy's. It depends.
Those sessions are pretty much workouts.... depending on the duration and how energetic the participants are and who is in the lead...I call it sexercise... a mix of exercise and sex.
I used to monitor on my watch my heart rate and the number of calories burned, and check the stats afterward... easily 500 cal burned and the heart rate spikes at some point ... you know when it is...
When the session is a fiasco the number of calories is way lower... LoL
What do you need after a workout? Water and proteins...
Once done, I usually stop by the nearest place and grab 0.5 L of chocolate milk and a Gatorade or water ...
With a few repeat SPs, with whom I can predict a good session, I share some nice chocolate that I bring with me on the way in...
It used to be cigarettes but I quit. I still think that a nice cigarette after sex is priceless.
YMMV
