Fingering & Gas???!!

So a couple of days ago my bf went really deep with his finger and it hurt like hell but I felt like I was gassy. A couple days later we have sex for the first time and I also feel like gassy but like queefing. Today he went down on me while fingering me and I think I might’ve “queefed” on him, but like WHY does that happen? It’s so annoying because I think about that instead of enjoying our time together so I’m not fully there. PLS HELP I know it’s weird and I haven’t seen anyone post about it but I just don’t want to keep going through this
