Ime, people who are curious about anal and want to try putting something up their butt aren’t big enough to take cucumbers (or at least they think so, you’re stretchier than you realize), and people who can take larger stuff have actual toys that are better in every way. Although, as improv dildos, they’re actually not bad imo. Better than most everything else I tried when I was a curious butt noob

try it out, see if it feels real or more like a joke
