Nervousness after dating for a month?

I have been with my man for a month but we have known each other for about 8 months. We are neighbors and never had sex until a month ago, i still find myself holding back in a few ways and being a little nervous and restraining myself from speaking my mind and even being more intimate with him. I really like him so i think that has a big part to do with it, Do you think this will pass soon? any advice on how to get through it?
