I dont know if its any different than you girls but mine before my ba were quite big when i was warm and smaller when i got cold (ovbs)
now after my ba they are constantly big and even when im freezing they dont harden and shrink 😐 but i truely think its because the implant is stretching the nipples out so im sure once the skin stretches my nipples will be able to go back to normal and shrink when i get cold, or tickled haha,
i worried about this too in the first few days then i looked at the pre op photo and they are the same size as they are now, just not getting hard xxx
