If feels like i have gas this is the 2nd time this has happened to me i'll have sex and it'll hit something and this my stomach blows up and i get these sharp pains when i move it feels like i have gas i went to the doctor the last time he told me i had a stomach infection i got better and now i had sex again and it happened again can't be a stomach infection if i happens right after sex. Can a condom get stuck inside and cause this?
