What can i do about vag gas?

I know what they call queffing or l farting is supposedly very common and i have had it happen before..a slight air released from my but not loud at all. Sorry if this is tmi but i don't know what else to do. So the past couple of times I have d I have been queffing ALOT. and very loud. They sound like very loud farts and it does not just happen one time; it happened a lot. So now I am afraid to let my boyfriend touch me or have . I am lucky, as he is very easy to talk to about this kind of stuff but the thought of this happening when we are together makes me want to crawl under a rock!! Now if they were just airy and very infrequent it would be less of a big deal to me..but they are loud!!! It is very weird b/c I have never had a problem with this and now all of a sudden...I can't find too much about it on the internet so i would really appreciate anyones info on this topic..thanks
