How to make vagina looser ?

So this is very embarrassing for me to ask but I know there are medications that make vagina tighter are there any medications/creams out there or methods to make it looser?

I am still a virgin (I am 28) and me and my boyfriend tried to have sex many times but it was just too painful for me. So last night he tried to use his finger instead to make it looser so we can have sex with less pain. But even that was way too painful I screamed, to the point that he doesn’t even want to have intercourse with me at this point as he’s too worried about me. He said I am too tight.

I am getting frustrated I was wet so that’s not the problem. Any advice?
