Possibly over reacting

Hey all long post I feel I may be over reacting but I cant shake it... my husband and his friend were talking and my husband sent a picture of me in a sundress playing with our dogs his friend asked if I was ruining a good sun dress with a pair of undies not sure why it matters but w.e he then said tell her (me) to live a little he makes sure his wife doesnt wear them she isnt allowed to.. so that doesnt sit with me right but to each their own if that's how they want to live cool. Yeah a nice long summer dress and no undies cool but when its WINDY and skirt is way above the knee and flowly and live in a community complex of little kids no undies no good but my husband KEEPS bringing it up almost like I have no say I need to not ruin them hes now said this 5 times INFRONT OF MY PARENTS we are 25 and have 2 kids I just have never mentioned anything to do with my intimacy time things around them I feel they dont need to know and probably dont want to know.. i dont know how to feel or how to express my annoyance with this without sounding like a dick but I dont want to start something if I dont really need to I just cant shake this feeling. We are moving to our first home in 7 days to be closer to this friend and now I'm a little worried about what the outcome may be we both are not drinkers like never once had one he had rum once and he was rude not a happy guy so I said no more but his friend is a drinker and my husband has already started to make comments of starting to drink and plans to get me drunk the 1st week we live there.. again im not sure if my annoyance and nervousness is valid and how to bring it up or just ignore it..
