Breast massage as a method of natural breast enlargement and breast health has actually been used for years as a means of stimulating healthy breast growth and promoting breast tone, pliability and firmness.
Here are some guidelines for breast massage you may want to follow:
1.) Use a olive oil or any other oil of your choice to help prevent friction and increase the enjoyment and relaxation of the massage for a more pleasurable and therapeutic experience. This can be an herbal mixture .
2.) Light to moderate massaging using a gentle back and forth gentle “swishing” action is best. This can be in a counterclockwise circle around the breast to help promote maximum lymphatic drainage.
3.) To gain maximum benefit and therapeutic effects, breast massage should be practiced daily, as part of a routine - perhaps when fresh out of the shower, since the skin is still somewhat moist and the room may still be steamy, for a smoother massage which may be more easily lubricated since there will still be moisture in the air. If you prefer, even several times a day can be a great benefit. It depends on what fits into your schedule. A few minutes at a time should suffice.
