struggle with sex pose

lol i hope this is an appropriate post to make here but anyways. im writing a fic with pretty vanilla smut and its mainly hurt/comfort other than that. its just what i like alright😭. and no i cant just write from experience because i have none, atleast not with another person :p. yes i have read plenty of ao3 and a couple of actual books but i still struggle and i have a specific question: i struggle to find a reference for this one sex position which is when, on a bed (its important that its a bed) a guy sits and the woman is on his lap kinda and riding him and her legs are around him. i dont wanna make things awkward by having super unrealistic poses happen on accident XD. the references i found, are those videos or images… were all on chairs but its just not the same is it. its a super weirdly specific question but its going to be my first published work after years of just reading ao3 so
