I really like oral sex so I´d say for me it comes first... The idea of getting the anxiety out of the way by means of caressing each other out with their tongues is just so appealing to me. For it to be perfect it needs to be followed by tender rough sex.
Many a time in front of my computer... there are urges one can´t control... the best time though has to be when a good friend of mine and coworker agreed on giving me a bj, that felt really good
