I am a 19 year old girl. I need some advice. I am about to get married and my fiance told me recently that he is interested in bondage, role play, and dominatrix. I need to know if these and other different forms of sex(anal, oral) are in any way unbiblical. Of course i would wait till after marriage and probably later down the married road. But is it truly biblically wrong to have sex in these ways?

thanks,
just wondering
