Slowing down the progress.
[QUOTE=Komo753;1977806]Copacabana or centro, everywhere is not safe when it is empty, just avoid empty streets better to stay in an apartment where you can bring girls if you are looking for an apartment next to Mabs or avenida Atlantica next to posto 5 just pm me, most hotels are not girl friendly if they are you have to pay a fine. Most love motels are not good always an issue (cold water, not totally clean, sheet missing, or bad bed) if you bring a girl there you can break your mood and girl's mood.[/QUOTE]Not a fine but more so a small amount more than if you remained in the room alone. It has never been an issue if the hotel is girl-friendly. At check-in, simply ask for double occupancy. This way there would be no extra time at the counter for each encounter.
When you say "most love motels are not good. " this can create a negative feel or connotation to the experience. I have used such facilities in Copacabana, Lapa, Centro, and Niteroi and have never experienced any of the problems that you mentioned. I haven't experienced problems of any kind for that matter. If there are love motels that aren't comfortable and present a climate of unease and an interruption of the progress ("getting to know one another") then by all means, this would definitely be the place to share such specific information regarding those locations.
