My birthday

So I'm 15 turning 16 and I've been dating my boyfriend for almost 3 months but dated him before this and known him for the past three years I just don't know if I wanna lose my virginity to him and like some times he would pressure me about it but then others he'd be like take you're time but then today he started talking about when we do do it he want to try anal and I kept insisting no but he said just try it and I said what ever and he consistally wants to try to finger me but I don't like that but he doesn't understand I have a couple problems I'm sure there's more I just can't think of them rn but what should I do?
