Sexual excitement in real life comes not from the actual acts but instead from the massive sensations related to them. Having a woman take my cock in her mouth does not itself excite me. It's the feeling of her tongue brushing the underside of my cock as her lips nibble on its tip, as her gums slide around it and her breath applies suction.

Ask yourself, which one seems more erotic?

1) She spreads her legs wide for her man. "Please, give it to me." He thrusts with all his fury into her body.

2) Her knees buckle, but she holds her legs open with her hands on her thighs. She is open, vulnerable to his touch. She whispers, the slightest moan, a request: "Please, give it to me." He grabs her body, feeling her heart race, her breath pace, as he engorges his tip into the parted lips of her pussy, as they wrap around his cock. The tight squeeze engorges his cock, as ripples of mindnumbing pleasure overwhelm his nerves.

The oft-overused mantra "Show, don't tell" remains especially relevant when it comes to erotic writing, because erotic writing is all about feeling the character's journey. Recall the feelings of an encounter. Use them to your advantage.
