I live under a bridge…

My bridge is the only way to reach a lush green field. Everyday people try to cross my bridge to get to the field but I always scare them away. The thing is the other day 3 goats tried to cross my bridge. I let the first goat cross because he let me blow him off. I let the second goat cross because he mounted me and gave me a bloody good rogering. The third goat kicked me in the belly and my ovaries popped. What am I??
