hymen breaking on second time having sex?

I'm 15 (please don't judge me) and I lost my virginity about a month ago, and there was some blood but nothing too bad. and today I had sex with another boy who had a larger penis when I got up after blood came flying out of me. Is that my hymen breaking??? because I have never seen so much blood in my whole life. and is it possible that my hymen didn't even break until the second time? because I thought the hymen was something else and now I'm just so confused and when I read things online they don't make any sense. does this sound right?? can someone tell me is this sounds right?
