Hi, I'm new here and would LOVE any help figuring this out. About a month ago my vagina started letting out air (queefing) almost every time I sit up from lying down, which is incredibly embarrassing. This has never happened before outside of sex. I've tried researching it but mostly I just get things about queefing during sex, which I've already accepted, but not every single time I sit up! I can't even push the air out because it seems to just come right back in, which is why if I kind of do sit ups and don't get up all the way, it will happen over and over again.
More importantly, I put my finger inside myself to feel what was going on and it feels like there's a gaping hole inside my vagina. There's a TON of air or space, it's just like a big cave - I can move my finger around and not touch the walls of my v, I'm not sure how else to describe it. Is there an explanation for why this would suddenly happen, and what can I do about it? It's both embarrassing and worrisome and I feel like it will feel different for my boyfriend when we have sex because I've always been relatively tight, but now it's like a cave in there and you have to dig around before finding the walls. For some other info, in case it's relevant, I'm 23 and on the pill and I never exercise but I think I may have lost a little weight because I don't eat that much, and I haven't had sex in a few months. Please help!
