I believe I might have Vaginismus?

I'm currently 20 years old and I think I have Vaginismus. I've been trying to have sex with my boyfriend for the past 6 months however we have been very unsuccessful. I'm a virgin and have had oral/manual sex with him and other people but never sexual intercourse because of my fear of pain. I'm not afraid to be naked or shy to get sexual but when the time comes to attempt actual intercourse I tense up. I was molested as a child but over time I feel that I have gotten over it especially since I like being sexual. When my boyfriend tries to enter me, I dry up quickly and have to continuously reapply lube. It doesn't hurt but I get tense and make it nearly impossible for him to enter. How can I overcome this problem and finally make love to the man I love? Any tips or tricks so I can get over this fear and live a normal life?
