Counselors need to be much more concerned with sex education counseling. By providing professional training for sex education for counselors will improve this situation. There are six licensed counselors that participated in this study. This study explored sex education awareness from an 18-month training course. The data were collected from focus group interviews about the training course. We conducted a qualitative analysis that summarized our results and findings. The results of this study were divided into two sections: counselors' awareness sexual education themselves and the sex education awareness of others. Each section included cognition of conflicted feelings, emotional awareness, and actions taken after awareness. The researchers found that counselors had constructed and re-constructed the cognition of sexual educational issues through the training course. Moreover, the anxiousness and guilt decreased when they were faced with sexual education issues. We also found that counselors improved their own sexual relationship and changed their method of intervention for sex education guidance on line. From the results of study, we learned that counselors should have experienced awareness and reconstructed sexual education issues about themselves before they became professional sex counselors. The results of our study suggested that providing to professional assistants and sex educators merits further study.
