lecture on masturbation

Before this lecture on thursday 26th febuary, i always considered masturbation to be a subject that was never discussed in public, except with ones partner. I knew we all do it as it has become a natural act in our lives. We discover ourselves before any one else can do so, because that way we know what we like and how we like it. Everyone is different, in order for a sexual partner to please you, you yourself need to know what does it for you.
Atleast this is my experience that my boyfriend after a year and a half, is still learning how to pleasure me like i can. And like wise i'm still learning how to please him. i'm talking about mutual masturbation where people in a relationship pleasure each other instead of themselves, and this does not involve intercourse.
