I (23F) just "lost" my virginity today

I'm embarrassed to share this, but today I lost my virginity to an object I have on my desk in my room that's shaped very similar to... (you know the one). Despite the pain and the slight bleeding, it wasn't a bad experience. However, I felt strange this afternoon; my appetite for food even changed. I felt a little guilty, and I don't know if I regret it or not. It's something I didn't really think about; I just did it. In my family, all of this is taboo, just like other things in my life, so I've always turned to my very, very close friends (it's been practically just one friend). I'm feeling very low, although I think it's also because of other things in my life... Likewise, I'd like to know if what I did was really right.
