Husband not interested in sex. Consult.

Hi, when I married I was 27 and vergin with no sex education . My husband can hav sex with me only if he watch porn otherwise can't,and that to when I ask for sex.In this whole thing i was not at all satisfied .He started  manipulating me this is actuall sex . After 1year inlaws started pressure ofhaving a kid then consulted a Gynecologist who told me about actual sex and my rights and suggested to meet a psychologist, after meeting a psychologist within 2 months I got pregnant coz he stopped masturbating for a while . When I got pregnant he started taking advantages and keep on saying iam Man(Mard) I proved myself and I don't need to meet any phycolgist or sexoligist . Iam 6 months carrying now and my husband still watching porn and masturbating, I explained him this is not the way he agreed to treat it . Give me suggestions should we wait till post delivery 2mths (6months)or we can consult as soon as possible . If we have to consult, to which specialist should we consult.Thank you.
