Hello,
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.
