Sex or not Sex?!... (Patreon)

In a boyfriend/girlfriend relationship do you prefer if the main couple is already having sex or not?! I think both scenarios have their merits:

If they are having sex already, it allows for nice comparisons between the boyfriend and the lover.

If they are not having sex, it's also hot watching the (probably virgin) boyfriend, not having any, while his girlfriend is already fucking someone else.

So what do you prefer?!
