I urgently need to be able to turn off my bi son.

Hi, my 21 year old son came out as bi when he was about 18. I was okay with it and so were the rest of my family. He knows my son's bi, but it doesn't seem like he wants to date men. He's dated a female before, and so I'm just wondering WHY WE NEED TO KNOW IF HE'S BI?<br><br>He literally flaunts it in our faces constantly. Whenever we plan something, he makes sure to the let the people present know that he's bi and that he doesn't have a problem with it, neither do we. The only problem is that he feels the need to let everyone know about it. He’ll just randomly blurt it out sometimes, and he’ll just say “just so you know I’m bi and I’m okay with it.” And I’m just sitting there like, I didn’t ask for this. I feel so uncomfortable just watching him do this, and I feel even more awkward when he just starts talking about it out of nowhere.<br><br>Does anyone have advice on how to approach this? Like please tell me how to make him stop. It’s getting to the point where I really want him to just stop. We get it. You’re bi. That’s fine. Please just be quiet.<br><br>Tldr; my son keeps telling people he’s bi for no reason, how can I get him to be quiet?
