So, I picked "A mix of everything". However, it was the only option that fits my view on this.
I am absolutely not in favor for straight up, interactive, XXX porn. Already played those games and they get pretty boring after I realized that there is really nothing more then picking a position and smashing buttons or shaking the mouse to it... no pun intended.
I would rather like to see much more interaction with love interests outside of sex scenes in form of dating, like doing side activities with them. Add little stories around the love interest, allowing an interactive glance into their lives, with little twists and turns, which might (or might not), cause us (or them) to question the relationship. Or the little twists and turns could also bring the player in rather risky, or even dangerous situations.
The sex scene itself does not need to show me the genitals interacting with each other, or with other body-parts and orifices. Some sort of mini game, to manipulate the strength of the pounding or the position, would be way too ridiculous. I don't think Cyberpunk 2077 is supposed to be played one handed...
...and lastly, some tasteful erotic, in a sense of the love interest wearing sexy clothing and/or behaving in a flirty/suggestive manner, can also spice it up a lot.
Here an example: The love interest could be an exhibitionist. To score, the player has to go streaking with him/her. Over time, the love interest gets more risky, and before you know, the player is streaking in the most dangerous parts of the city. This eventually gets the love interest so fired up, that sex becomes available. It also poses the challenge, that the player must avoid gangs while streaking, in a manner of a hide and seek mini game. If the player gets busted, the date is over.
As final sex scene, player and love interest could get in on in a bush, behind a fence, or some other hidden place in public, and all the player gets to see are some people walking by, being irritated about the strange noises.
Again, just an example.
