Is it ok to touch your own breast?
In private: your hand, your breast, nobody else's business.
In public: If you are a male, nobody would notice. If you are a female, you should not make breast-touching obvious.
Ok here's what you do take your hand and with you fingers touch your breasts if they have hardened they will feel hard. If by chance they have hardened take a meat tenderizer hammer place one breast on your counter top and hit your breast with the hammer as if your were tenderizing a piece of beef. Repeat these steps for the other breast.
