Help with teachers and mistakes

Really dont know what to do?
Before I start I know most of you will say "he should be arrested or hes a pedophile" but wait please,
i have an english teacher called (mr gill) john, it started about 2 months ago I was having a tough time at home so I was acting out at school (detentions,punishments,timeout etc..) but it started up again 3 weeks ago and I wasn't doing my work he kept me behind and we talked for about 10 mins and we Just stared at each other after talking, I said "i think I should go" and walked out and I think maybe the 4th I was in his class and he kept me behind and said he was worried about my work and behaviour and Again we stared and I kissed him on he lips and he kissed be back (properly) and I walked off totally confused and now I think it gone ma-bey to far but yesterday I came into his class and said I want to talk about it and he agreed but I didn't want to talk about it in school because my best friend is Always with me at dinner and breaks when I meet up with her so I said meet outside of school it will be easier so yesterday I went to his house and I was cautious just in case because I know what your thinking... and we talked and agreed not to do it again and try to be totally normal and when I was leaving we stared again but longer and be kissed and it lead to sex (my first) and I feel guilty today but I don't want to report him because I didn't say no and I honestly wanted it to happen as much as him so I don't know it going to be so awkward on monday now. I don't know what to do? x
sorry I keep posting this but im so stuck!!

im 14 years old

The problem is the law says there is no such thing as consensual sex between an adult and a 14 year old and for good reason. Adults have a great advantage over children from their experience. That goes at least double for a teacher who is paid to understand young people and help them, not take advantage. The adult is the one who is supposed to have enough self control to avoid such a situation. Inviting you to his house tells me it was planned. There isn't a reputable male school teacher in the country that would do that.

You don't know if it's happened before but I'll guarantee you, if nothing is done it will happen again either with you or another student. If you can't deal with your parents being involved, find a female counselor or teacher that you trust and have her help you get through this without your idenity getting out. You absolutely can't remain in his class.

It's your choice but I'd blow the whistle.

Wow I am 12 and I have never heard such a thing how old is this teacher????
He should know better I mean kissing and sex and btw y did u go 2 his house?? I noe it was 2 talk but if u sed noe 2 him 2 hav sex nothin could hav stopped him 2 rape you you noe. That's dangerous. Now you've done it with him, he might bribe you by saying if you dont have sex with me then I wont give you good grades and levels. Wat you've done is seriously bad and bad for yourself.
