am i loose?

Hey guys. This is super awkward to ask but here I go. I'm 18. I've only been with one person. I was sexually active ages 14-16. When I lost my virginity, it didn't hurt at all. Just slid right on in. Also, my partner (and myself) could easily fit two fingers inside my vagina. Once again I've only been with one person. It made me super self conscious, because I thought your first time was supposed to be extremely painful, and I thought maybe two fingers would be too much, especially since I was so young. Is there anything I can do to tighten up? I would always ask my ex if I was loose and he would say that I wasn't, but I always assumed he was being nice
