My man doesn't go down, I've brought it up but...

Laura • After many long years I`ve found the love of my life n I`d love to give him a family❤️
My bf n I can't get enough of each other and have an amazing sex life but he NEVER goes down on me! I don't know why either, I've told him I like it and he's said he doesn't mind but he never does... How can I get him to go down??
