The first? Or the Second?

I've only had two physically sexual partners. My first sexual experience being with a bff of mine. I was a virgin at the time and I agreed to be his fwb. During our sexual encounter he gave me a good fingering (😍) but we didn't have any actual sex. My second sexual encounter was with my bf and we've had actual sex (penis in vagina). So my question is who did I lose my virginity to, should it have existed?
