Talk to Urologist on Burning After Sex

Any Dr here? I'm facing severe burning right after intercourse with my husband. It's sharp painful feels like my vagaina gets reddish and swell, and it lasts almost 30-60 mins. if needed to pee quick it gives burn while urination too. Otherwise in normal condition I don't feel burning or smell during urination but yes my vagina itches. I'm married since 8 months, pcos and my lmp was 18 snd there are 5 days up now I'm feeling pain waves of periods but don't getting it yet. And pain waves are more likely to appear in vaginal point and appearing less in lower abdomen, pain waves are also very sharp that it drop me down in few seconds. Help me Dr! 😔
