My husband and I have just started TTC and this will be our second month. But it's not going very well because every time we have had sex lately, he goes soft. He starts out hard and then BAM-nothing. And nothing can get him back hard again. He's struggled with this throughout our entire relationship but only every once and a while. Since we've started TTC it's been just about every time. It's sooooo frustrating.  But I can't tell him that because it will only make it worse. I know it's probably the pressure of TTC that is putting to much pressure on him. Had anyone else had this problem?
