need advice! Embarrassing

So me and my boyfriend We're having sex in the doogy style position and we're going quite hard and next mintue he says he's cumming and I'm thinking in my head, I am to. But whilst we were having sex there were moments when it felt great then felt like nothing, so he finishes and I turn around to kiss him and my vagina lets out the loudest noise ever and I'm so embarrassed so I just try to ignore it. Then he goes to get a drink so I open my legs and lay down and the rest of the noise comes out lucky he was at the other end of the house and then a whole bunch of liquid follows, I know why the sound came out, because of the air from thrusting in that position.
