I've been writing a comic book resently and had to actually think about the onomatopoeia noises to put in. I find this rather hard and ended up having to google most of them to see what others had put.
Then last night I was reading a Yuri anime and I started paying more attention to the onomatopoeia noises they put in.
For like heart beats they put - budum or doki doki
then the sex noises are just the generic - ahh errr ekk e.t.c with a few slaps and slurps.
So my question (if you wish to share) is can you onomatopoeia your sex noise?
I'll put my one up later, got to get my partner to actually tell me what it is first I rubish at putting sounds in onomatopoeia form.
