Suggest Remedy For Difficulty In Penetration During Intercourse

Hi , I m 24 years ,married woman. It has been 3 months since my marriage but still me and husband have not had vaginal sex. My husband tries to finger me but it is causing extreme pain since I don t like it and I m not getting properly excited. He is hesitant to try with penis stating my vagina is too tight. When I urge him he seldom tries and loses erection stating it s painful for him to enter me without dilation. But he is able to maintain erection while giving blowjob. To be honest I have no prior experience with fingerings and I m a virgin. For the first month I admit I was fearful of the idea of sex as simple caressing near the vulva too created pain. But now half a finger enters with quiet pain but the progress is too slow and lowering confidence of me as a wife. Can you suggest a solution.
