It depends. I might have sex first, then relax. Or I might roll a joint. A couple of shots of rum and listening to music is another way. But I don't really like listening to music too much these days. I make a living out of people listening to music out of equipment that I design and sell as it is.
I like to perform at peak perfection. A spliff before action only makes you lethargic. And it is no good if you intend to have a long spell exchanging body fluids.
I usually just watch movies whenever I am stressed out. I prefer comedy or romance movies since they're lighter and not stressful to watch as compared to horror or thriller movies.
I also enjoy watching television series. Right now, I am quite obsessed with "The Voice" and "The Big Bang Theory." And yeah, cartoons as well like "Regular Show" and "The Adventures of Gumball."
Lastly, just going on social media and going through my newsfeed is relaxing for me, lol.
