What do I say during BJs and Sex?!

Im a dude, & I’m not sexually active at all. It’s a morality thing for me. Yes, I’m Christian, but I’m not judging anyone because at the end of the day we are all sinners. I personally am just waiting for marriage or the girl I plan on marrying. But I’m getting closer to getting back in the dating scene and finding the future Mrs. But I the issue is I have no clue what to say or do during it all?? Like I have watched adult videos before ( not so much anymore, again a morality thing ) but surely that’s not how it is irl right? Idk. I’m just curious and confused. Ultimately when I do get there, I don’t want to be an awkward person for her. If & when that time comes.
