My favorite places to breed is the park, the shed next to the lake, basically any room of my house, the abandoned house in the woods, in the bushes next to the lake
I've named a few before but I'll put in some ideas again, my best and ideal spot for me in my teens was our shed in the backyard , secure and had locks, would sneak out there about everynight for fun. A private and reclusive area in the woods is also lovely.
