Help please?

Well im not sure what to do. I am 21 and in ny first relationship. We will hit a year and a half at the end of this month. I always told myself that I wanted to wait to have sex until my wedding night, however I recently have been finding this difficult. Im really nit sure what I want to do. My boyfriend is much more experienced than I and he has been so patient with me. Can anyone give me advice? Should I go on and give him my virginity or continue to wait even though it will be extremely difficult? My boyfriend is always talking about it, but i know that he will never really pressure me into it. (Just another reason I love him) Thank you those who have took the time to read this and give me help.
