This matter still needs two people to discuss. Tell your wife what you think and let her know that you can't accept her taking private lessons. If your wife explains to you that she is actually taking private lessons only to exercise and the coach respects her, then you don't have to worry too much, or you can go to the gym with your wife. After all, seeing is believing. If you really can't, go to the gym to get a card yourself and go to the gym with your wife to exercise.

Finally, I recommend a more extreme method. If your wife really doesn't listen to you and doesn't want to change her current coach, then go to the gym by herself and find herself a coach of the opposite sex. Remember not to choose the same gym with your wife, so the other party will have all kinds of fantasies. If your wife cares, she will definitely feel the same way and will change coaches according to your words. Of course, this method is not very recommended. After all, it may cause family conflicts. After all, many girls and boys can do something by themselves when they are in love, but they are determined not to allow their other half to do it.

If the above two methods don't work or you are still worried, then discuss with your wife about changing coaches, and find out which better female coaches or more comfortable male coaches you are familiar with yourself, so that your wife can learn from this coach.

In fact, it is now a society where men and women are equal. In fact, men don't need to care so much about it. Or think again. There are still many male doctors giving birth to women. Do you still insist on a female doctor when your wife is in labor or not? There is no need to think of all relationships so complicated. With the continuous improvement of social governance in recent years, the current coaches are actually more disciplined than in the past, and there are few such particularly greasy men.

I wonder what you think of your partner's hiring a private tutor?
