i've never used an aphrodisiac, but once at a sex toy party, they were selling this perfume with pheromones in it. whether or not it actually contained them, i had no idea, but i really liked the way it smelled so i bought a bottle. i was out with a group of friends but we were all scattered around the bar. none of us had more than one drink yet. i told one of the guys about it and he liked the way it smelled. he put some on his neck to see what would happen. then he went up to where a couple of our friends were talking and joined the convo. a couple minutes later one of them said she just wanted to kiss him, and she did.
coincidental or not, we laughed our asses off.
