It is like playing fire especially if one day they will meet in the real world. Also, if men have more female friends, they will easily get unsatisfied with their existing partners. My partner is one of the examples as the ladies who contacted him would send him photos which they had worn deep V top or in very alluring posts. I had mentioned to him that if he keeps on doing that then it is the end of our relationship. However, this goes on for 5 years already and NO CHANGE.
