Then I have your answer for you.
Just like any fetish, vacuum pumps are not for everyone. They actually feel rather weird, and many wouldn't like the sensation. You can try this by bringing the glass or a cup to your mouth so the rim makes a tight seal, and sucking air from it. Feels not very nice, actually.
Many wouldn't like the visual effect of engorged parts too.
As for steroids - for many people chemicals is a big turn-off and a no-no. So even less women will be into it.
