Hello.. I am married since 8 months and during intercourse penis is not able to get inside my wife vagina. Most of the times it slides and my penis is more thick versus the vagina hole of my wife.. even when I insert finger inside my wife vagina she used to feel discomfort hence I don't continue it further..But now she is comfortable.. we have used Durex lube but it drys up very quickly once we apply it first during foreplay.. now we use coconut oil.. We do enough foreplay and are sexually aroused..when we focus only on copulation of penis and vagina we are not able to enjoy the sex time..what do you suggest where the problem lies? Do you have any doctors in Sector 45 Gurugram
