Not involving feelings, remembering that it is something you’ll usually do, going with a clear mind and taking everything as roleplay, in other words, she won’t be your girlfriend, nor will she be available 24 hours a day for you. As such, you have to go with the flow and enjoy yourself without limits, in the end she won’t judge you.
Secondly, getting the rules clear before beginning, what you like and what you don’t so that in the moment of action, things don’t get cut short.
Thirdly, choosing a place where you feel comfortable for the encounter, because you’re naturally going to be nervous, the ideal thing is for you to be able to concentrate and feel free, you should choose a faraway place where you know no one is going to turn up or see you with the girl.
Fourthly, if you’re married and going to be unfaithful, think about doing something with the escort you wouldn’t do with your wife out of pity or nerves.
Fifth, if you don’t know how to break the ice, she probably will, escorts have more experience than us.
