Another point is drugs and alcohol. If you and your guest can do without both, so much the better.
Otherwise: use as few drugs as possible before and during a meeting in the job, since they also limit the ability to think and control.
Under the influence of alcohol and drugs, it is more difficult to assess risks, dangers or emergency situations. Always remember that you are responsible for your own health. In particular, keep in mind that in emergency situations you can only help yourself and should avoid drugs of any kind.
When working with sex, it is important to be awake and clear-headed and to show a certain concentration. For example, there are reports that customers have tried to secretly remove the condom and penetrate it without rubber (e.g. in the doggy position). For your protection, it is therefore always important to be attentive.
