The reason you can't smell it is because it mostly smells of you and the other person's body odor, which you're too used to to notice in the air unless you leave the room for a while and come back.

If you're having quiet sneaky sex, maybe under some blankets, you're not gonna create a big stench. If you're working it the fuck out and you both end up drenched in sweat, don't expect the two bodies whom did that not to produce some smells.

Think about it this way: the smell of sex is the smell of two people exercising in a small space, but without the pussy dick and ass stink being subdued by pants and underwear. Smell your balls, smell your arm pits, smell some pussy; that all together is the smell of sex.
