Vagina noises

Here's the thing, when I first started having sex My vagina would make funny noises like if i was farting, and I actually felt some air coming out. Once I had sex for a few more times the noises werent that frequent and disappeared after a while. After 3 months of lockdown I finally met with My boyfriend and it happened again. Sometimes when I masturbate happens too. I don't know what that is or if it's normal or what is causing it to happen. Tell me if you've ever expierienced something like that.
