I believe the most important part of nbe is to massage your breasts with oil. Twice a day for 5 minutes. Recommended oils are coconut, almond, aloe vera and fenugreek. Fenugreek is usually sold as pills or seeds, but oil is available. If you use fenugreek (for best results) it must be mixed with one of the other oils, preferably aloe vera, about 3 aloe vera to 1 fenugreek. Apply just enough oil for it to be completely absorbed in the 5 minute massage. I don't believe the method of massage is important, only that it should be gentle and not too vigorous.
Noogling should be in addition to a massage routine. Use one of the oils (the thicker ones, coconut, thickest, or almond) as a lubricant and should be applied generously to allow your breasts to slide easily into the cup. Drink lots of water. Good luck!
