Which of the five senses is your most erotic?

For me, it's audio. There's something about hearing a woman during sex that really turns me on. I'm not talking about the screamers and dirty-talkers either (although that certainly has it's place), but just the little moans and gasps she makes as she becomes aroused and approaches orgasm. For me, that's a huge turn-on.

I would say it is a tie between touch and hearing.,

Scent. Back door to the brainpan.

It is very close to scent and touch.
Both rapidly intensify in the moment.

Scent is absolutely the sexiest. The scent of arousal is unmistakable...

Touch and scent. Occasionally, hearing other people do it (in hotels) has flicked the switch for me, but not often.

Sight and sound, because I love seeing the rippling of flesh and the contortions of faces. The deepened arch of a woman's back when you pull her hair in doggy. Or her chin touching her chest when you pull it from a front facing position.

Sound compliments the above with the moans, grunts and profane words that litter the air. The slapping of flesh combined with the wobbling sends me crazy. The slurping of me eating her or her gobbling me.
