I have a paragraph as follow:
Knowing what to say to women is the most common concern among males who are unsuccessful with them. They obsess over every single word, phrase, and possible response ahead of time. It is an inevitable result of traditional socialization, as it makes males feels inadequate for or intimated by women, while at the same time reducing their natural ability to tolerate uncertainty.
I understand the meaning of word "obsess", but I don't understand it in the paragraph. Can anyone help me? Thank!
