My boyfriend cant stay hard, he cant come and he struggles to get it in, help to?

Ive being seeing a boy for a few months and a few days ago we decided to have , I'm not a virgin and i thought he wasn't either, everything was going fine until he couldn't get it up, i didn't think it was a problem, so he masturbated and finally got it up, so we were 'doing it' and then things just went from bad to worse, he went soft inside me, he then couldn't come. So we decided to leave it and try again later, we tried again later and this time he couldn't get it in at all, so we swapped positions (me on top) but nothing, so we tried one last time with him on top and he puked all over me, once we sorted ourselfs out he told me he was a virgin, he hasnt spoken to me since.
