I have trouble holding a conversation with guys I don't know well any advice?

Lol just keep asking questions even though you might be interested. Asking about movies and interest will make him think that you're interested in him.

Find out one of their hobbies. You don't really have to be interested in it, but if you at least appreciate it, you'll score major points. For example, I was talking to someone I worked with and I got into a half hour long conversation about his interest in the civil war. I'm not really interested in the civil war but I realized that people are quite willing to talk about things that they're interested in. So, find out if they really like movies, or underground bands, or the civil war and just ask a simple question about it.

There really isn't any secret to talking to someone. You should just talk to them like you would a normal friend.

Ask him questions talk about movies, sports, tv etc. Just be open and don't think so much that'll just make you nervous say what is on your mind then it'll become easier to talk to guys.
