One of the biggest drawbacks of having large breasts is
gravity's tendency to do its thing - it's a particular worry for the natural-breasted in this, the age of sillicone. It's one of the most frequent reasons I contemplate surgery every so often, and one of my biggest body hangups. But all is not lost - I'm working on my pectorial muscles (which in turn will make my breasts look firmer) with various
chest exercises which don't even require a trip to the gym.
