I am scared (inexperienced) - he didnt really go inside me

Hi " My last period was on the 29th of march last month ,as much as I remember and now it did not arrive yet. Me and my boyfriend played stupidly I could say now (!!) , and he went on top of my vagina , we never had intercourse but he did opened a bit with his fingers (2) , am saying that thinking that my vagina , because of my excitement as well could've gotten wide enough for when he played on top ... Didn't get in , but I did felt like it was a bit there and ..now am thinking of pre cum (he did ejaculate but took it off my vagina when he did so and I saw that ) , thinking of pre cum as I heard it is almost as dangerous as the big sticky ejaculation, and I'm afraid that maybe that got it's way in ....my vagina . I'm really scared , as I haven't had my cycle yet...and I'm expecting it .. Please could you help me with some of your thought regarding to what I wrote as information to you so that I get some help , and peace of mind , as maybe there s noting bad ..nothing that crosses my mind ...:(( ....????? Please please help ..and thank youuu
