Taking tampons out. Advice?

Putting it in is no problem. Taking it out though, even hour later when it should be full, is always hard. I thought that after 5-6 hours, it should be full enough to just slide out. When I do see it after its out, it looks full.  Everytime I go to change it, it's always some struggle to get it out. What could I be doing wrong? Advice?
