Discomfort or pain during s*xual intercourse or penetration may occur, even when it seems like your body is ready. If penetration is very painful during s*x, you should find out what the cause is and what can be done about it. Here are some reasons below
Women’s difficulty with penetration is sometimes attributed to vaginismus, believed to be a strong, involuntary tightening of the vaginal muscles, a spasm of the outer third of the vagina.
Some vaginal infections—like monilia (yeast) or trichomoniasis—can be present even when you can’t see any signs. The friction of a penis, dildo, or finger moving on the vulva or in the vagina might cause the infection to flare up, resulting in stinging and itchiness. Herpes sore on the external genitals can make friction painful.
