Confuzzled

Okay so in January I went to a party and this guy was there that I was really close with and we were going to have sex (I was a virgin at the time) and being that I was a virgin obviously I was tight so he couldn't really get it in.. It only went it like 1cm so we gave up... Later on in the year I was with a different guy same thing happened exept it started to hurt a lot but it was hardly in only like 3cm so I told him to stop... A couple of months after that I had sex with my current boyfriend and it went in all the way.. He lost his virginity to me and he always gets upset because he thinks I lost my virginity to the guy at the party but idk who I lost it too...Would that mean I lost my virginity to my boyfriend now or the first guy I was with at the party ???
