Tight Vagina

I am nearly 20 and I am still a virgin! I recently bought a dildo and it is my second time using it and I still can’t get it in, this time I used a condom on it and heaps of lube in me and on the dildo and it still hurt too much - I had already had an orgasm so it wasn’t an issue of being too tight - id love some advice so that when I do lose my virginity it won’t be such an issue

Thanks heaps
