did i lose my virginity? should i take plan b?

so yesterday, me and a guy i’m dating, were making out and hands went everywhere (i really like him and so i was okay with it) i felt him cum a little when i was giving him a hand job, and then we tried having sex, but since it was my first time every time he tried putting it in my vagina it was just not going in... i was on top of him, idk if maybe it was cause his dick was small? or cause i wasn’t wide? or because of my hymen?but idk if i should be worried about taking a plan b pill...? i’m not on birth control and he wasn’t wearing a condom.. and i don’t know if that’s considered losing my virginity? i wouldn’t think so.. but any thoughts? oh and like an hour later, he fingered me and i bled so i’m sure that was my hymen.. but im just worried if i should take a plan b pill? because i heard of pre cum... but since his dick didn’t even go in my vagina, i’m not sure...
