Mari is 33 years old and has been married for 8 years. When I was a student, I was a shy guy who was interested in sex, but I was in a rather serious group. I had my first sexual experience in the summer of my first year of college. After getting married, I was not blessed with children, and because of that, I got tired of having sex with my husband and we have been having a lack of sex recently. I wanted to have various experiences after turning 30... but my desire just grew.
