My husband has a small dick.. Help!!

Kdot
So my husband has an average/small dick and for years I was fine with it. After this last year, I've been starting to miss having a big dick when I have sex.. With my husband, I can only cum when my clit is stimulated but when I have a bigger and thicker dick, I cum almost instantly and I miss that feeling. I just feel like sex with my husband is so much work sometime and we've tried different ways to spice it up and it's OK but like I said.. Just feels like a lot of work. I just want to be sexually satisfied and right now I don't know what to do. I masturbate to big dick porn when I can... Ugh! Has anyone else ever felt this way? What advice do you have??
