Knowing his libido, it might not fade, not for him at least, so much as become more manageable over time. Right now, at the beginning of new discovery, Steve finally had an understanding of why everyone seemed to put so much emphasis on sex. It was different from taking care of his needs himself, but it was more than that; it was that physical connection, the ultimate physical act of intimacy, seeing your partner abandon themselves to pleasure and knowing you had done that, made them feel that way.

Steve listened to the noises Rogue made, hearing them change pitch as she got closer to her release, his own breath coming in pants and occasional whining moans. He was getting closer too, but he was going to make sure Rogue came first; his control slipping slightly, his hand clenched where he held her buttocks, leaving what would eventually be spectacular finger-shaped bruises, that he'd both feel guilty about, and be vaguely fascinated by, in a horrible sort of way.

And then she said his name, and said she loved him, and all Steve's well-meaning intentions went right out the window. He gasped, grunting slightly as his orgasm shot through him, his hips snapping forward in jerky, uncoordinated movements, clutching her lower body against him and grinding into her, before his muscles slowly started to relax.
