From reddit: Drinking coffee (caffeine in general) makes me horny and I don’t know why.
"Not trying to be a perv. Am I alone on this? It’s not the act of drinking it but a side effect. I just had a Starbucks drink and I’m uncomfortably horny at work and it happens every time. My bf and I joke about it but sometimes it’s so strong I want to go to the ladies room and rub one out. Has anyone else experienced this?!..."
