Husband Seems To Prefer Porn To Sex

Hi Everyone
I have been married for a very long time and up until about 2 years ago also had a reasonable sex life but now we hardly have intercourse, partly down to my low libido. My husband has a very particular satin fetish and likes me to wear blouses and skirts, blonde wig, glasses and very long finger nails. It's the same thing every time and has been for decades. I do not feel even remotely attractive when wearing this stuff and normally it takes about 40 mins to get ready so there is no spontaneity. We never have sex unless I am dressed like this and I am so bored with it all now. I feel he can only become aroused if I am this ' character ' . He knows how I feel but just dismisses it.
Also I have always known he uses porn which doesn't bother me but recently I discovered just how extensive his collection is. Huge box files filled with images from porn mags, some of which he buys online. He also has DVDs. I feel it's becoming an addiction and he seems to prefer this to any intimacy. It's left me feeling pretty rejected and upset.
In every other way my husband is the most considerate and loving partner but sex has always been on his terms and it's all about what he wants or needs.
