I don't think the fall from grace of Speedos has anything to do with inhibition, it's just fashion. People wore them a lot during the 80's and so everyone relates them as the trunks worn by their parents and older generations, (which just ain't cool).
As for the other thing, i think you're just imagining it.
I've never had a full body massage, but i think if i did i wouldn't expect them to rub my full body. It just means more than just arms, or legs, or neck etc.
