What would help him go in me?

My boyfriend and I have been together for almost 3 years. Since he lives out of state, we haven’t done the deed in 2 years. He is coming to visit in a couple weeks, and I am sure the deed is going to be happening. I am excited and ready for being intimate again, but I am afraid he is not going to be able to go in if you know what I mean. His package is not as small as it was when we did it before. Is there any tricks or advice that would help him be able to go into me?
