I feel so guilty about this, am I a pervert.(long question, please read the whole thing).?

I am a 14 year old male, and I am a sopre in high school.I always feel guilty about things. For eg., i once slightly tore a page of a book in a library, and i felt guilty for a very long time, and i once felt guilty over hitting a car door with my car door and I kept thinking that maybe i did it on purpose. I have a twin sister who is the same age as me (15 as of this month).. One day last summer (after my freshman year of high school), I got mad at her for some reason while we were playing a video game or something and we got in a fight, or tussle or whatever you want to call it(I started the fight) During the fight, i grabbed her crotch. Ever since, I feel disgusted with myself and very guilty about doing that, and i keep thinking that I might have meant it ually. I really don't think I know if I was thinking something ual or not,and I am also scared that maybe I was thinking something ual and I don't want to admit it.I also remember thinking right after I did it that I might have been ually and i felt disgusted with myself. I don't remember if I really was ually or not, but I might have been. I just want to be normal and get rid of all this guilt. But the uncertainty is killing me. I felt guilty about thing's before, but nothing quite as bad as this, because I feel like I really did do something horrible this time. i don't know what is wrong with me.I want to take responsibility for my actions, but I don't want to be some weirdo kid.. I started feeling guilty like a minute after I did it, and I've felt this way off and on for about 6 months. I feel so disgusted with myself. I think molestation and are horrible thing's and I feel so terrible that I did something like that.I really feel so bad.I can't live a normal life like this. Also, I know I touched my sister's crotch on purpose, my guilt is because I is have been thinking something ual before or while i was doing it.BTW, I have talked to my sister about most of my feelings about this, and she says that she doesn't think it was weird and she think's I should move on basically. But I still feel guilty that maybe I somehow hurt her deep down and she's just lying to make me feel better. I sometimes feel like I'm just as bad as a child molester or a rapist, and that im a horrible person.What should I do?,. Please no spam comments, i'm serious and I'm not spamming. i've posted this multiple times due to account problems and bad answers and I had to edit it. I just want to be normal again. Please help. I am asking this because I want to know if I am really a horrible, perverted person, . Please be honest, don't say stuff just to make me feel good or better. Besides, I forgot to add, since my sister and I are twins and we were homeschooled until we started high school freshman year, we have always been very close, and since I was very young to right before we went to school (12/13) we took showers together and saw each other naked and all that. I know it sounds weird but since we were raised together I guess we just kind of got used to it. Our parents did tell us that we should grow up and stop showering together, but we didn't actually stop until we were around 13., of course we don't shower together anymore, but I also keep thinking what if I thought or did something sexual way back then, I know we both have touched each other when we were naked when we were younger,(around the age of 10-13)and sometimes i feel guilty that maybe it was sexual. I keep feeling these doubts and fears. Do I have a problem? Am I really messed up and perverted? I don't want to hurt anyone, I just want to be normal, I don't want to turn out to be a molester or weirdo. also, does the fact that I started feeling guilty like the moment after i touched her crotch or maybe even while i did it mean that I really did mean something sexual? Because i remember thinking the day I did it that I could never forgive myself for what I did,, I'm just so confused and kinda obsessed over this. Also, by definition, does this count as molesting my sister or ? That's the something I hate, and I would seriously hate myself if I ever did that, and now I feel like maybe I did the unthinkable,and I hate myself. Also, could I get into legal trouble for this? I'm really scared, I don't want to hurt my family in anyway with all of this, I just want to be at peace again. Please help.
