Yes. The gym is an easy place to cheat.
Going to the gym is a very popular thing in today's society. People nowadays are becoming more and more beauty conscious and are starting to pay attention to their bodies, especially married people who will have more free time, so that means they are more likely to choose to go to the gym.
In this place, people will be very loose in dressing in the first place, and when men see these, they always like to move some hands and feet, and after a long time, they will have some bad behaviors.
Likewise, if you're a woman, the gym is a place that exudes hormones, has all sorts of people working out in it, and is filled with masculinity.
If you don't have confidence in yourself, it will make your girlfriend feel like you don't trust her, and it will also keep you in a constant state of anxiety and irritation, which may also result in fights between the two of you, which is not conducive to the development of your relationship.
Over time, a vicious circle is formed, and it is also easier to cheat.
