Because I personally still have heavy traditional ideas, and there may be some male chauvinism in my bones. If my girlfriend has more muscles than my arms, then I don't think I can show my desire for protection. Many people may think that I am male, but I am actually a girl, so I can't accept it myself. I have a lot of muscles on my arm.
I think it's a good thing that my girlfriend loves fitness. After all, fitness can not only shape her figure, but also be good for her body. But if she exercises more muscles in her arms, even more than me, then I feel a little useless. Of course, I don't want to satisfy my strong self-esteem in this way, just saying that everyone has different ideas.
Falling in love is to find someone and yourself to accept the future life, but I think we must satisfy both sides on this basis. If I find a woman of the opposite sex exactly like me, I can't accept it. I hope there are more complementary things between two people to make life more stable and harmonious.
Of course, there is no way to accept it. On the one hand, if I like it very much, then I think it is understandable, because after all, everyone has everyone's hobbies. Just from my point of view, I can't accept this.
But life is your own. If a person can accept all the things he doesn't like about you, it proves that you two are really suitable.
