I see lots of tutorials on socials and blogs that suggest to cut low end to gain headroom to achieve a louder master, this is a very wrong approach for different reasons.
You don't gain headroom cutting low end, at least till you start to go higher (from 40-60hz and up).
If you cannot hear something doesn't mean you don't need it.
The reason you don't hear low frequencies can be a consequence of your listening system. If your speakers are not good enough to reproduce something, you cannot ear them, but listeners may have better systems or just something with a wider range. In this case your songs will sound weird and different from other professional masters.
We don't feel the music with our ears only. That's a fact, we perceive music with ears and bones too. Did you ever went on a concert or a club? Even classic music have very deep low frequencies, all that vibes are able to give use huge emotions to listeners, so you may want to have the right ammount.
Not every song need to be the loudest song in the world. Mastering is not about achieving numbers (LUFS), but enhance the song till you reach a "commercial" level and a good balance that make the song to play nicely and coherent along other songs of the same genre.
Anyway, if you cut low end because the song sounds better there is nothing wrong. A low cut is like every other eq curve, something that must be used to improve the song sound.
