Is my boyfriend's son a conceited shit?7

My boyfriend is living with his 19 year old son. His son is a huge man whore. He's pansexual so he thinks he can just bring whoever to fuck. He's always fucking someone. My boyfriend doesn't care because hes just grateful to have a place to stay. Everyone can say what they want but his son is a gross man whore who just fucks whoever offers. I was spending the night at his son's with him and got up to pee. I see his son talking to one of his guy fuck toys. The guy was saying how he used to be homophobic and never saw himself sleeping with another dude but how what my boyfriends son did with his tongue drove him insane... Gross. His son asked that guy"What do you think? Will you be back." The guy says "Yeah, definitely but as far as you and everyone else knows, I'm straight." Then my boyfriend's son says the most conceited thing ever. He says! "Okay. You can be straight 6 days a week but I get you on Sundays." And boops that guys nose then kisses him. Seriously idk how my boyfriend put up with this shit!

I am not homophobic. Idc what people do with their lives. He's just always fucking someone over here.
