Hi, this is a wonderful website. I too masturbate on a regular basis. I am 40 years and at the height of my sexuality. I usually masturbate just using my finger, slowly moving it in a circular motion. Since I have very large breasts and nipples, I love it when my nipples get erect; it is a wonderful feeling.
My best technique is using the end of my hair brush and inserting it into my wet pussy. I do this while playing with my nipples. I will masturbate just about anywhere. When my lover and I are together, his favorite thing is watching me masturbate while he stimulates my nipples. We have done this a few times in public...no we have no shame. When I with him, he likes it when I wear a tee-shirt with no bra. My nipples are always erect so you can see them through the tee-shirt. Sometimes when we can't wait to get home, we'll fine a dark public place and go at it, usually we do this in a dark movie theater. He plays with my nipples, while I masturbate. I LOVE IT!!!
