She has guy friends?

Long distance relationship, and my girlfriend has guy friends and talks to guys, which makes me very uncomfortable. I told her to stop, but she don’t wanna stop because it’s her friends. Which I don’t understand why she needs attention from other men. They were two guys asked her to go for a run together. I told her that it would make me uncomfortable if they would do that she didn’t go for a run, which I am very grateful for, but some other guys asked her to study and she wanted to go study with them, the trust is very important in a long relationship. I told her it’s OK as long as it’s in a public place and not privately. But I do worry about this all the time if there’s a guy always there. I feel like I would want to be the only man in her life, but she said that she wants her friends. it could be that she only friends regardless of gender. But as a man, it does make me uncomfortable and honestly, I don’t know if this is normal because it’s my first relationship too. I just don’t wanna be controlling. I want to set boundaries because I do stress a lot. I do feel like it is creating a lack of trust when she talks with other guys, and I mean, privately as friends. But it could be, for example that she met someone in school and they are friends after just meeting and I’m not OK with that hanging out with guys. This is destroying the trust that we have built. Because then I worry and for me, for example there’s no problem with stopping talking with the girls. I don’t want to make her jealous, but I don’t know. Maybe she doesn’t understand that it’s making me jealous and creating a lot of trust. I need advice. I don’t know what to do.
