Virginity

I I'm 20 years old and I  had sex for the very first time last week.  I don't know if I made the biggest mistake of my life due to the guy that I lost it with isn't my bf or anything like that. I told him that I decided to do it with him because I liked him but I wasn't sure what he felt. He said he wasn't looking for anything at the moment. Which I kinda already had a feeling he would say that. So we agreed just to stay friends for now. I don't know what to think of my actions. All I know for sure it's that I'm stupid for not waiting to actually lose it with someone special.
