Hi,
Since I don't have a picture I can't say its herpes or not, if its herpes you can able to make out by blister, tiny crowded red dots or eruptions.
Along with pain, in some cases with mild discharge.
If you strongly feel its not herpes.
Other reason for abrasion is
1. Infection in vagina bacterial, fungal
2. Dryness – due to infection, improper foreplay can cause dry sex and redness, pain, abrasion,
dehydration due to
diabetes or decrease water intake, age factor,
hormonal imbalance
3. Forceful sex can cause injury, yes for you it may be the reason 4. Foreign bodies due to unhygienic sex, sex toys
5.
vaginismus - anxiety during sex can cause pelvic muscle construction and cause pain
6. Eczema.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. S.R.Raveendran,
