Hi, Yesterday I Was Sexually Active With A Guy. Although

Hi, yesterday I was sexually active with a guy. Although he didn't go all the way in he did put the tip in (it hurt too much) I bled when I was going home (Ive had sex once before) and it kindve irritated me. Today however I checked myself down there and its a bit swelled up with this white like ball around my vagina entrance (some liquid substances is leaking too) it doesn't hurt too bad but enough to get me concerned. Any thoughts on what this could be? Please help.
