The first time with someone is special because… well, because it’s the first time. Because it’s novel, because it’s new, because you’ve got those butterflies that you get when you’re about to do something worthwhile. Like the first time you open a new book or hear the first few notes of a new piece of music, the excitement is in not knowing quite what to expect. It’s a milestone, as well as an experience. I’ll never forget the first time I felt you inside me, or the first time you held me after as we panted and grinned together like idiots.
The next few times still carry some of that same special quality, and all as at the same time you’re slowly figuring each other out, getting more comfortable expressing what you want, having the enjoyment of getting better at it. There’s still that little bit of tentativeness, but that’s nice too, because it means you both care about getting it right.
