^This, unfortunately.
Pop culture articles always say that you can compensate by just eating it or fingering her to kum, and that will be fine. That advice is dead WRONG imo. When they want the D, and the guy is unable to deliver, it is usually game over. Even if you make her kum by other means, you still lost major points.
A LTR will probably forgive you for having a bad night. But a ONS/FWB/plate generally won’t. Worse than that, they discuss this with their gf right after, and she’s probably not going to take your side on this one either.
This isn’t to make you feel bad. You can certainly try again. All we are saying is don’t be shocked if you have to meet a different chick and let this one go.
