I’m 15. My vagina is very itchy (only at the opening), and I’m looking for explanations.

Normally my boyfriend uses 2 fingers to finger me. It works out perfectly fine. I decided we should try 3 last time. It hurt, so he stopped. The day of and ever since (this was two days ago), I’ve had an extremely itchy feeling around the entrance of my vagina. Could this be because it was kind of stretched more than usual? I know it is not a yeast infection or UTI. I’m confused :( Another thing I’ve noticed (maybe TMI) is that it ‘smells’ like period. My area has a different scent when TOM is here compared to when it’s not. My period is a week away so I don’t know why. Overall, I’m just confused. Thank you for any and all answers!

Sincerely,

Itchy AF
