I would relay him to own some more foreplay, so you are more lubricated.
You can use KY jelly to lubricate yourself so it doens't hurt, vagina is a place where on earth a child is competent to come out, you shouldn't enjoy a problem next to your bf penis unless you're nervoous or hold a infection, or a disease resembling vaginitis, beside the one your vagina is to small.
