Susan Murphy and Ivorygorgon, While I am super sure your opinions are very much appreciated, please try to conceive that there are some things that you just cannot possible understand unless you have lived it. It is very much possible to go through life wanting larger breasts, not because society says we should, but because we just WANT them. It may be as simple as a personal preference.
I do agree with Smoogy...wearing certain clothes (like sweaters) seems to make us look fat (or is it my arse that makes me look fat

)
I have never had any problems with working out as far as bouncing goes. I think you have to go pretty big for that to be a problem. How many cc's were you thinking...if you don't mind me asking.
I started back with cardio after 4 weeks of recovery and did lighter weights. I think it took me 10 days of working out before I was back to my usual weight load. However, I left the chest work out completely for a few months. I, too, said I'd only do light chest work in the future because I was happy with my new chest. But after a while, I couldn't help but pack on the weights again.
Some moves that really felt super weird for a long time (not painful...just so weird)...tricep dips and lying tricep extensions. I cannot begin to describe how weird those felt through the chest. It goes away with time.
As for recovery, it depends on the person and placement. Unders take longer because of the trauma to the pecs. I say it feels like your breasts are engorged with breast milk and there is a huge blood pressure cuff around your chest, fully tightened.
Never once during my recovery did I feel it wasn't worth it. I've yet to think it wasn't worth it! I'd do it again 1000 times!
