i like to call body parts by their correct names, right from the start. even when my son was a newborn, i'd tell him that i needed to wipe his penis when i changed his diaper or bathed him. i'll use vagina/vulva with my daughter as well. i think that if you use the right names from the start, there will be no embarrassment.. "that's your nose, your elbow, your penis.. ".. nothing to be ashamed of! it did take some practice for me to get used to it though..... i come from a very repressed family as well!
as for showering, i think it's all a personal choice. if you feel comfortable, go with it!
