I've been doing coke regularly for around 3 months and this idea came up to me recently. I think mixing it with lubricant before sex would be a great way to get it directly into my and someone else's bloodstream but I couldn't find any info online and I don't want to end up ruining someone's vagina trying it. Would mixing my lubricant with a line or 2 of coke be very dangerous and would it numb our sensations near the area? Has anyone tried something similar?
