I'm so stressed out !

Please I'm so in need of help! I have an appointment with the doctor on Friday but I just need some advise.. I'm scared I might have vagnisumis 😔 since I got married I have had painful sex, my husbands penis won't go all the way in! Only the head will go in. I just got treated from clamydia and the doctor said we can have sex, we used protection and it still won't go. Only the head will... it's stressing me out and I don't know what to do! My husband dosent deserve this 😔😔
