I don't think it's on Republican agenda right now, this more sounds like Democrat doing, Democrats currently being the biggest hypocrites and puritans, although I don't think it's of primary interest for both parties.
And to be frank, this may sound weird, but if they do, I will learn to live with it. Like if they cancel alcohol, and you can live without alcohol.
However, I don't think they will ban oral or anal sex. That would not pass ever in the eyes of nation.
