What can I do to stop obsessing over all of this?
Maybe you can realize that
The human brain is completing the incomplete information you get with an image that exceeds over and originates in your worst fears. In bright colors, beautiful settings, fantastic experiences are put together by your own mind. This is what especially happens to the male BS. These images FAKE per definition.
1. Most people have an average sex life (which is really nothing to be jealous off)
2. Most people are in the affair fog, living in a fantasy, in their mind
with fantastic sex, even though in reality it is really sickening banal.
3. Most people would in the affair fake mutually how great the sex is and go out of their way to prove that to the other partner, and want to believe that themselves.
Now if you realize this, you can counter the images you have by transforming and exaggerating elements of the images to ridicule proportions. Change the place to a pig hole, change the light to cold blue light, provide them with disgusting flabs of fat on all the wrong places, enlarge facial features, ears nose, etc. The new images will make you laugh and feel pity for them.
And you know what? Probably the cold reality is more like your new images.
