But especially for your first time with him, you need to stretch it out, make it amazing. When he does something that feels good, show him with your body, let him hear it in how you moan. He needs to know what you like and want, and you need to read his signals that hes giving back. That way, you two can continue pleasing each other during the entire experience, making it better for you both. Tell him you how you feel about him.

Both of you need to simply focus on doing what you know your partner likes and reading them for more hints on what to do. That is what makes sex truly amazing.
