I didn't really masturbate much until I was prepared to admit just how sexual I am in the months after my marriage came apart. Once I had done that I found myself masturbating more and more, especially when not getting partnered sex. My favorite approach is to undress, bathe, talc and perfume myself, often using body lotions.
I then get the mood right. Nice candles, romantic music, dimmed lighting, maybe a pretty robe or nightie. Then I get settled on the bed and begin to indulge in a nice fantasy and stroke and finger myself. Sometimes, if that is not enough, I roll over onto my tummy and press a nice little satin pillow between my legs, and I get some really nice climaxes as a result.
