Something that causes you excitement in a sexual way. Turn off can be the opposite, or something that makes you not want someone sexually.
It was a total turn on/off to watch him take off his shirt in the hot sun while he was installing some gutter guards.

Basically something that disgusts you, find embarrassing or unappealing (mostly) about the opposite sex.
1. Lisa: "So, my boyfriend and I had sex for the first time last night."

Natalie: "Really!? Oh my god, how was it?"

Lisa: "It was okay... but when he started climaxing, he farted! It smelled so bad!"

Natalie: "Ew!! What a turn off!"

2. "There was this random girl who danced with me at the party last night. She was so hot. But when she grinned at me at me, I noticed she was missing two front teeth. Immediately turned me off, man."
