painful sex help

i recently lost my virginity nearly a month ago and i cant seem to enjoy sex with my husband fully as it gets really painful at some points... i try to bare it for as long as possible and we try it slow and fast plus different positions but the sore ache pain doesnt really go i do feel pleasure at some points however but the pain is still there

last night and this morning was the worst it ever got it was worse than the actual night i lost my virginity as my vagina has been aching all day. Is there something wrong with me has anyone experienced this while getting used to sex? My husbands of average size and nor am i allergic to sperm is there anything i should be doing besides using tons of lube?? also havent been able to orgasm while im having sex please do give any advice thanks
