Hi! Ive Been Married For About 2 Years And Im

Hi! Ive been married for about 2 years and im still a virgin. We have tried intercourse but my husband doesnt know what to do and also i get quite scared of the pain that intercourse might cause. Due to this my husband doesnt even bother trying anymore. What should i do? Is there anything i could take to help me relax or help my husband with some guidance? We would like to have a child but my fear discourages him to even try anymore. Please help!
