Such vaginal tears may be due to vaginal dryness which may be due to lack of foreplay before intercourse, medical conditions such as vaginusmus and pelvic pain,vaginitis,anxiety regarding performance,low estrogen levels,inflammation and infections of vagina,menopause and drugs such as narcotics, tranquilizers, nicotine, alcohol and sedatives.
I feel that pelvic examination by a gynecologist along with cervical swabs and hormone studies are necessary. Please get it done.Also indulge in foreplay before intercourse and use some lubricants like such as KY jelly, or moisturizers, such as Replens or Senselle or vaginal estrogen creams.Also keep your pelvic area clean and wear cotton undergarments. Regarding surgery for removal of scar tissue, it may help but in the long run the surgical incision may itself scar.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I've just read your post which was from over 18 months ago so I'm not sure how you're going with it all.
I'm 31, and have exactly what you have mentioned. I've had it for 2 years and have had a break of up to 3 months from sex. Also with a long term partner.
After sex a split appears which has been diagnosed as an ulcer, it seems to heal, or become not visible after around 5 days. I've had a biopsy which showed non specific ulcerative tissue. I've tried multiple treatments and I'm about to book in for surgery but I'm really worried about it..
I'm hoping you've had some success, and if so, what helped!?
Really hope to hear from you :-)
