We have been together six years. And sex is becoming an issue over the last year or so my bf has practically stopped wanting to have sex. Wont even bring it up wont initiate and views it as a chore. I have tried everything to make him want to. I try to do romantic things. Ill flirt drop little sexy hints to him thru the day, make the setting romantic, suggest we go to stores to get new things to enjoy, surprise him with outfits, even the more forward walking into the room naked and just simply asking if he wants to. All to no avail.
In fact its been causing huge fights. Hell ask wtf is wrong with me why I want to so much. To stop asking and do something in stead of ask. But when I try to say set the mood or dress up its always " I dont want to". When I try to say touch him in ways to put him in the mood " stop, what r u doing , I dont want to " so im getting yelled at to come up with new things and ways to put him in the mood but then im getting yelled at when I just ask.
Its making me feel very insecure and unwanted. And in our recent fights he says " thats all u want. Why dont u go be a porn star." "You know why I dont want to its fing boring and stupid" to which I will ask what he wants from me to make I not boring which leads to more yelling and name calling.
I dont understand what im doing wrong and why its soooo terrible of me to want to be with him physically more than once a month if im lucky

I feel lost, sad and completely unwanted what am I supposed to do
