Yeah m talking about the same thing
I get it you are talking about the flexible shapeless one maybe
M talking about a straight catheter tho, it might be with or without
Those bumps
beginners use the normal ones since the primary function is to delay ejaculation
And then after getting used u can use one with bumps and so on
And same I GOT VERY FREAKED OUT TBH WHEN I SAW IT FIRST
But -_- literally there are so many weird stuff that i m fine now

Oh tbh There are MANY i have read with that kind of stuff as i didn't save them
But sadly enough i can't recall names as such
One of them is -" if you hate me so" but there is only one scene of that thing being used and it helps second couple to hook up
THO THE MANHWA IS BEST HAHAH
I feel sad now i should have saved them ༎‿༎ now i CAN'T reread
OMFG I JUST SEARCHED UP GENITALIA BEADS AND PEARLING SINCE SOMEONE TOLD ME THAT THE BUMPS ON THE SEME DICK WHERE GENITAL BEADS!! AND PEOPLE ACTUALLY DO THIS. I EVEN WHEN THROUGH THE IMAGES Σ('◉⌓◉’) AND IM TRAUMATIZED
