Dont like my husbands guy friends

I do not tell him who he can and can’t talk to or anything of that sort. But i do tell him all the time how much i do not like or respect his friends on any level and i don’t appreciate the behavior he allows from them. He has a friend named matt. he is a gamer friend. they have only ever met 1 time. Matt is a cheater, very toxic and doesn’t respect woman or other’s relationships. He tried to bribe or brag about his sex life and sex encounters to try and make my husband jealous and want to be single. Matt also talks about (in detail) the sex he has with other woman to my husband as well. They cannot have an actual conversation that doesn’t involve sex, cheating, or another female. And because of that i do not like him. I think their conversations are so inappropriate because my husband is perfectly fine talking about HIS past sexual relationships with his past woman too with him. I feel so degraded and disgusted when i hear him talk about that stuff with him guy friends. he calls it “guy talk” but he also talks like he wants to be single or something , gets so caught up with these past woman in the conversations. He never talks about me to them. his own wife. I’m also 7 months pregnant so i’m even MORE insecure already. His friend matt wants to come visit him and i’m soo close to tell him that i don’t want him seeing him . i feel like he’s going to try and pressure my husband to do something disrespectful. Am i tripping out or am i overreacting ?? i just don’t understand why my husband would want company who act like a child and can’t even hold a conversation that doesn’t involve sex and woman, and constantly tries to ruin our relationship. And when i approach my husband about it , he just says “that’s just how he is”. like the excuses..
