Thanks so much for the replies, and welcoming. 

 I am new here, and hope to really learn a lot more about increasing total breast size, not just nipples.
I think I will do the smaller one first for a month and see what happens. 
I received them this week and tried it on the smaller nipple, but it kinda hurt too bad. I was already sore before trying it out.  I have to heal from a rather umm,  aggressive lovemaking session with my bf before wearing them.  
I did read that in the booklet Wannabe,...  my nipples are no longer pierced. Have not been for almost 10 years now. Having only one in for a few years, and it being such a large gauge, it left it bigger than the other. If I knew that was going to happen, I would have kept them both pierced the same.
And I will try the cocoa butter,   I love coca butter lotion!
Peace and Love.
