Extremely painful burning after sex!!! 😭😩😫

UPDATE: I'm 16 weeks pregnant with our second baby and have never had this issue before!! The last 3-4 times me and my husband have had sex, it burns like someone lit a damn match in my crotch. It's immediately afterwards and continues to do so for hours after. I've been in contact with my doctors office about this issue and they think it's just a yeast infection (so they prescribed a cream) or his semen irritating me. They said to try a condom but that's just not an option for us. Please tell me someone else out there has this issue and has had a successful solution!! 😭😩😫😭
**AHHH makes me a little nervous that no one has had a successful solution.. Besides ice packs and heating pads😜 which I'm all for! We don't want to use a condom because it just simply interrupts the moment and they friggen suck πŸ™„ we're married.. Shouldn't have to use one nor buy them either. I hope you understand πŸ˜•... I'd rather just stick an ice pack between my legs πŸ˜‚ Also we will try lube.. I never thought the friction could be an issue because I'm always wet.Β 
I have my monthly check up today with my doctor to check baby's heartbeat so this will be a topic of discussion today with her and I'll update if she comes up with any magic solution!!Β 
***Doctor said to try lube because even though I seem wet it probably isn't inside causing friction. She said it'll probably continue to the end of the pregnancy 😩 I told her about the heating pad and ice packs and she laughed and said she hadn't ever heard it before πŸ˜‚ thanks for al the input!!Β
