Is my boyfriend gay???

So I went to my boyfriend house (he knew I was there) but he was not present, and we do not live together. I went to brush my teeth while waiting for him to return home. As I was looking for toothpaste I noticed he had hemorrhoid cream as well as a half gone tube of lubricant. That instantly made me suspicious only because I found text messages exchanged between him and a guy who openly told him he was bi.. (attached below) He is very good at deleting things so you cannot really tell what all the conversation was about. But I am beginning to really wonder.. also in the bathroom trash was a glove that has poop on it that looks as if someone might’ve cleaned their butt hole out. 😷😷😷😷😷😷😷😷There was also a glove full of what looked like liked lubricant. We never had anal and when discussed he said he had never had anal. Hell we only have sex like once a month, never had sex at his place. Asked him SEVERAL times if he was into men which he denied or joked about but was never upset when asked. Has anyone ever went through this? Any advice or tips.. I’m getting pretty paranoid about it and wanting to call it quits but I’m trying not to jump the gun. 😬
