Depends on what type of bullshit.
On one end, if the bullshit is just "my partner wants me to give a fuck about them", and you don't want to have to do that, then decent sex might be enough to make you consider changing your mind, if you're also compatible in other ways.
On the other end, if the bullshit is "my partner has psychotic breaks and chases me around the house with a chainsaw", I don't think any quality of sex would really merit consideration in the bigger picture, given how short your lifespan might become.
So, there's something of a scale there, and it partly comes down to what you personally consider bullshit to be. People won't agree on that, it's a personal thing.
Usually done with shotguns, it makes the pellets spread out more. This reduces the need for accuracy when firing. Another, bigger, part of it is it makes the gun easier to conceal. Normally weapons small enough to conceal are less powerful, this lets you conceal a bigger one.
