Here is a post on this problem that I was having. I had a picture in the post of the pump. See if you can get a model of the pump from your Dr., it really helps!

I have the Titan touch. I had a really "hard" time getting mine to deflate, I just could not find the deflate button. So I call my Dr. and told him my problem and he sent me a model of the pump. It is the actual size and shape of the real pump. That was all I needed, I could see and feel the release valve, one side had a concave shape and the opposite side had the little button. Now that I could see what I'm supposed to feel it is no problem finding it. It does seem to work better when I hold the valve and squeeze my dick to get full deflation, then I give it about two pumps. It even comes with a handy key ring
