It can also, dare I say, be quite frustrating for the woman in the relationship to do all the talking. Yes, it's our bodies going through most of the testing, poking and prodding, but it takes two to make a baby. Men aren't just there to provide the goods! As a woman, I need my other half to talk to me, communicate his feelings to me.
Talking about feelings runs the risk of ridicule and rejection. The idea of finally plucking up the courage to talk to someone about what is emotionally going on lays ourselves open and bare to others opinions and in worst case scenario judgment and rejection. What is more excruciating than chastising oneself for harboring feelings that aren't seen as healthy? To share these feelings and be judged and rejected by a family member or partner of friend. Who would risk that?
