Initiating Sex

I have been with my hubby for nearly 16 years and sex has been high on the agenda do to me not having a lot of body confidence or sexual confidence. My friend is in the same boat with her hubby so we have a pack with each other today that we are going to put out more and intiate sex more because we both want to but for some reason just dont do it.

Has anyone got any good tips on how to initiate sex and even though ive been with my hubby for so long i get scared and embarrested,
