the burning and irritation at the time of ejaculation could have to do with the alkalinity of the semen against-what used to be a very acidic hostile environment. if you are positive that the discharge is indeed coming for the vagina it could also have to do with this burning as it could be what is left after the vag walls are possibly affected by the semen.
brown vag discharge after hysterectomy and post mennopausal. i am 57 had a vag hysterectomy 20 years ago. i am also post mennopausal. i have been having a dark brown vag discharge for 8 months comes and goes without treatment. no odor or itching associated with this. i have also noticed a burning feeling throughout the vagina after we have had intercourse at the time of ejaculation. . i have been an rn for 30 years but i can't seem to figure this out. the volume of discharge at times is enough to leak through my undergarments. thank you for you input
