Is my boyfriend gay or what?

When ever me and my boyfriend are about to have , he alays asking me to stick foriegn objscts up his rectum, at first he was asking me to tell me to stick a finger or too, then slashlights, then berrcans, and now umbrellas. AT first I didnt think anything of it, Then I told my mom, she said, she saw him making out with my gay uncle at the movies , then I found a condom covered with feces and we dont have . I dont believe a man and a man should be together. What should I do, Break up with him??? help
