Yes - they can reach the spot perfectly.
We are toooo porned out - gay culture that is - to believe that only someone with 9 throbbing inches will really make the bottoming experience better for us. that’s false (for me).
Anything over 6” hurt mainly because I’m so tight. Went out to the clubs a few years back and met this short little guy who wanted to flip; he had a thick, veined 5” and when he put it in (doggy) he literally fucked the life out of me that night. I died and went to heaven: he hit my prostate over and over and over so good I shot a monster load (moaning) without touching my D. The experience was so overwhelming from the orgasm that after I came I immediately asked him to fuck me again. For the next 2-3 months we fooled around, I bottomed for him everytime, it was *that* good.
