Husband

So I am 36 I have 3 children to my previous partner iv now re married iv been with my husband 5 years we have never used contraception as I have always wanted another baby , we fell pregnant 3 year ago but I lost the baby at 12 weeks . I have tried and tried to get pregnant but just can’t . My husband won’t go to the doctors as he feels he’s not a man if he can’t get me pregnant , sex is now really boring as I feel we only do it when I’m ovulating .

What should I do . Xx
