Best way to negotiate barebacking
I will be traveling to Medellin for the second time in a couple weeks with the intention of barebacking at least one girl on my trip. In the interest of minimizing risk, I'm going to likely choose a relatively expensive prepagada from one of the online sites to do this with since I assume they have lower mileage, so to speak (also on PreP and will be bringing DoxyPep on my trip).
My question for those with experience: what's the best time to negotiate barebacking? For any other special request I'd ask ahead of time to not be disappointed later on but in this case I feel like I risk scaring the chica off if I do that. But if I wait until she's already in my hotel room I feel she might be more willing to negotiate now that she's already made the trip (also seeing that I'm relatively young compared to most mongers could help). That's my reasoning anyway. I won't lie, there's one chica I've set my sights on and I am determined to finish inside her and would be willing to pay a serious surcharge for the privilege and I really don't want to screw things up. Would appreciate advice from anyone who's negotiated this sort of thing in the past. Thanks in advance.
