Masturbation

In modern times, we have so many shows on television that talk about sex, sex activities, just general sex. We have them going on all through the day on certain channels. The morning chat shows, such as Trisha, always have some reference to sex in some way. Yet, when it comes to masturbation, there is little, or no discussion about the matter. Why is this?
People are very open to talk about whatever they do in bed with another partner. However, when it comes to what a person does in bed on their own, the conversation goes cold.
It seems that people are embarrassed or ashamed about what they get up to on their own. But, regardless what anyone says, everyone masturbates, its natural, isn’t it?
Also, if you think about masturbation as a sexual act, then it is usually the fist and perhaps the most frequent sexual act that people participate in. so then people should be more open about the topic, as they are like with sex. That’s just my opinion though…
