Sorry but if you've got breasts then you'll have to get used to guys looking at them. There was a recent study from NZ that found that 47% of men's first glances at a women were towards their breasts. It's just biology. Also take in to account your average male coder might not have seen any for a while - well it is male dominated (sorry - "got to wait for the liquidity event to have a liquidity event!")! ;)
wrt to asking your co-founders the same questions, my guess is that you are so paranoid about the "not looking in the eyes" thing that you appear unconfident and unsure, so people look to your co-founders for confirmation.
