we were very good sexually with each other at the begining of our marriage, but as i got pregnant he started losing interest bit by bit, until now 1.5 years after delivery we only get intimate evey 1 or 2 months and sometimes even more, i donot think that he has ED since i see him erected while being asleep. i think its me, i am tired of talking about it with him as he seems not interested, is my marriage over?
