Is this a bad sign?

Is it a bad sign if my boyfriend admitted that he has found clients and some of his previous coworkers he worked with attractive? He would talk about his clients at work with other coworkers. He wouldn’t talk about his attraction towards coworkers, but he was close friends with them. He has never cheated, but it just doesn’t sit right with me. In the beginning of the relationship, we established our boundaries... He said he thought it was okay to check out others but not talk to them. I agreed, except he has spoken to these people.... So I don’t understand why I wasn’t allowed to? I feel like I’m very loyal and respectful, but at the end of the day he does come home to me, plus he constantly talks about me at work. So idk if I’m making this a big deal. Maybe he didn’t establish the boundary correctly? He has introduced me to all of his coworkers at every branch he’s worked at, and everyone knows me. I don’t think he ever thought about cheating, but then again I’m pretty sure they weren’t attracted to him. I just kind of feel embarrassed, because I don’t think I would talk about my clients in that manner with my team at work. He always pulls the “boys will be boys” card, and how guys differ from girls, so I will never truly understand how guys are.

Edit: btw I totally understand you can say you think someone is cute or handsome to your friends etc. Without wanting to marry them or have sex.

...

But it’s to the point where he sexually objectifies women and does comment sex jokes and stuff like that. I should have clarified but this is what is confusing for me personally.
