sex to impress

this is very confusing and quite short,so basically, when I started my secondary school I liked him and he liked me,and then we started ‘’bebo messaging privatley’’ lol and e was sayn the usual shines blabla and im like no. and I dno why but then he started to hate me,and just piss me off in this particualr lesson everytime I had it,then we were buddy buddy again,and then one day he just came onto me literally at one lunch time,and was just feeling me up, and then we was tlakin after,and every so often we would chat but I dint really think anything of it because EVERY BOY IS A PERV at my school[even tha neeks] so about a month ago,we had SEX, it just randomley happend, he told me he wudnt tell anyone and then I realised WE DID NOT USE A CONDOM,[and the boy goes on and presents himself if he has many girls if you get me yeah], so a week later I thought I was pregs or had an std but dont worrry about that now,cause im not pregnant,and now its like all over the school ecause he told his friends with big mouths and one of his friends blackmailed me into saying who I had sex with I.e his friend,even though he already knew,he threatned to blab and he did!>:(, and like the whole school knows,inclding my cousin who I hate,[another story] and the girl that is my best friend ( we fell out over this to) knows and I dint want her to know, why did he tell and he knows everyone knows and is ok with it,but im not because im a girl and its embarrasing,and then earlier today I found out I took his virginity, what can I do, I keep denying it,because he is just one of them boys

what can I doo,its not really something to awnser to but some advice or something wil do :) lol
