Why sex after marriage is difficult ?

So my husband is not having sex with me and it very difficult to survive.
I have told him many times that this is something that i need to. But its same reaction and action . It feels like iam begging for it and he just gives it to me in some bheek.

Although there is everything else in my marriage. Love romance hugs kisses love you .
But sex that is out of picture .

Note:- he watches porn daily as if its his ritual . And that to a specific type of where girl have big boobs and touching herself .

How should i deal with this . Iam so confused .

Its been just 1 year to our marriage.
