It would be an unusual name, and I agree that it sounds similar to the girls' name "Lauren." I do know a man named "Loren," though. His name is also pronounced exactly the same as "Lauren," but he doesn't seem to have any problems, except that he sometimes has to spell his name for people, since they've never heard it before.
In the US, it's become more popular lately to give boys unusual names, so if you don't mind having an unusual name, it should be fine. I've certainly known boys with much more unusual names than that.
