My BF told me he has had sex with 2 men😟

So after meeting a guy I think I'm gonna marry,he dropped a bombshell. Well at least a surprise,to me.

He said back in college he did alot of drugs,Ectasy,cocaine...and that he and 2 other guys had sex. My BF told me he was on bottom,so let 2 guys have anal with him. That was it. One time thing. He said it was awful,and never ever again.

I know this guy,and I know he's not gay. I believe him.

What do you think about your guy telling you this? Do you think he's gay now? Bi? Just a mistake from 10years ago??

Not sure how to handle it.

He brought it up super casually,like it was just something he did on college,no biggie. I wonder how many other guys have at least tried something ONCE in their life. Interesting...
