Naturally, people do moan and make sounds, but some people take it to the extreme when they watch porn, and try to copy it. Deaf people moan and make noise, even though they were Born without the ability to hear, nor know what moans sound like.
Source: i’ve watched deaf porn. I don’t regret it. Shit was one of the hottest videos i’ve seen cause you know she is not faking the moans. She 100% means every moan and sound she makes. Lol.
Edit: Thank you guys so much for upvoting my new reddit account. Now i have enough karma to comment on other subreddits i’m interested at without having a bot remove my comment due to my low karma, and suspicion of being a spam account. I lost my old account, so i had to create this one a few days ago.
