Find how to make it yours. Your kiss is different from his, because yours has love, depth, and understanding. There is much more to it, thatn just a kiss.
Same with any sexual acts, you know it means more with you, because you love her. She loves you. That other stuff was just sex and fantasy. Not real life.
Try doing these things in a way that is different for you both. Make it mean something, but also new and different.
