Hi,
Since you mentioned its not the 1st time sex you are having, we can rule out
hymen break.
Other reasons for bleeding per vagina:
1. Infection- many reasons for infection, from a partner, not following proper hygiene, public toilets.
2. Dryness - infection can also cause dryness, improper foreplay can also cause dryness, menstrual cycle disruption.
3. Forceful sex or
masturbation can also cause bleeding and pain.
4. Benign or malignant polyp. can cause bleeding, need to meet a gynecologist as early as possible.
Other reasons:
5. Foreign bodies
6. Anatomical abnormalities
7. Bleeding disorders
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr S.R.Raveendran, Sexologist
