My lady wants at least once before we wed while I want us to wait till we wed in two months' time.Advise

We've gone for VCT but formerly agreed to wait till the wedding night which is just two months away. But now I see how disappointed she feels when I can't proceed beyond kisses whenever she comes to my house or whenever I visit her. She has once boldly requested for it while kissing her and preparing to leave her appartment. Please advise.
