Have committed some sexual stuff like touching and kissing to opposite gender at age 7-10, but I don't know what should I do? I am 18 now and have been suffering with regret and remorse from 3 years

When I was a child 7 years old ( BOY)and aunt used to live in neighbourhood she just i don't know she calls me to play with her son but i found her behaviour very weird like she try to seduce me a lot a lot . I am 18 now and when I asked my mom about her she said that she used to call me every time. A similar case I went through in my school that a teacher took my hand and rubbed on her lap for 16 or 15 seconds. And a similar experience again when my English teacher used to comment on me and she was also weird she used to touch me and once she hugged me like her under clothing was purely visible .I was also introduced to sx at very young age i thought that Cuddling kissing and touching is Sx my childhood was also not better I had family problems and my mom dad used to fight.

But unfortunately I don't know I was attracted to those acts I dont know . I was just feeling good and then it put a severe impact on me and I did some similar thing to other children (7-10) as I was also with their same age

I don't know but I did very disgusting there was no se*ual intercourse or i loosed my virginity no but i did like kiss touch, and now as a 18 year old I am regretting and have very remorse full thought I just don't like myself I am suffering from 3 years my parents don't know this

I am also regretting that if they will blame me in future to those who I did these . I am blaming myself also

If possible please advice me or can help me 😞
