The F sound is usually a labialdental fricative in English. So you are putting your bottom lip on your teeth and letting some air go by to make the F sound.
English has bilabial plosives where you touch both lips together and let air stop for a moment which makes the P or B sounds.
English doesn’t have a bilabial fricative so you might be doing this in your dialect and it doesn’t stand out to anyone because it doesn’t otherwise have a phonetic meaning. But, interestingly, in other languages a bilabial fricative has distinct meaning from a labial dental fricative. I believe I’ve read that in Japanese the “F” in “Mount Fuji” is actually a bilabial fricative and not the normal F that English speakers use.
In English, my lips touch when I make the “f” sound at the start of four. I am also pretty sure they touch for one.
Nope, for me my bottom teeth touch my upper lips.

My upper teeth touch my bottom lip when I do.
I cover my bottom teeth with my bottom lip at the start so the lips touch on ‘four’
I’m not sure about this. The only way I can make my lips touch when saying that number is if I actually say pour.
Thought the same, but you’re right, putting both lips together makes a plosive.
