This is so embarrassing to ask you about sound which is related to having sex.
Is there any sound related to breath? I think "panting" is quite far from implying sex.
I found some words like; boom, bang, smash, thump but I want to find something related to sound.
If I can't find the alternative things, I may use some words like "ah", "mm" ..... so weird.
You wouldn't dare to say like that, if you know I'm tired of listening your panting every night.
This is what I made, but it doesn't make sense.
