Not that my opinion matters here, but I think as long as they are not rock hard, I don't think fake is so bad. Mine are fake, but they are 11 years old & now very soft & natural looking.
I've recently seen pics of a lady who's boobs are so hard & just plain weird looking that I'd think it would be doing her a disservice to show them off. Ack!
Gotta be careful when shopping for new titties, ladies.
