no it is not normal to have pain with vaginal sex especially three years after a c-section. i would strongly suggest that you see your gynecologist so that you can be properly examined to determine why this is happening. hi as you have not said have you changed partners since your c-section and is your new partner on the larger size penis wise or has your partner been doing some pe exercises so he now has a longer and larger penis apart from that cant think why this is happening. so suggest just get off to your gyno let him do some tests. do hope this helps. good luck
i had a c-section about 3 years ago when i have sex it hurts whenit hits i'll say it's my wall. it that normal
