We're new to this and I don't know if rimming is something I care to do. Is this something men have come to expect? Fron the amount of pictures and videos, it sure seems that way. I know I can always say no.
My experience is not that it's something anyone expects.
My first time was when we were showering together and I told him there was something I wanted to try, which is a pretty easy way to get over squeamishness.
