hi..ok i'll make it to the point..
since i was 3 or 4 ..i used to make some kind of behaviour that i dont understand till now .. i used to sleep over my pillow and keep doing a fast and strong moves till i fill some kind of satisfaction..
now as i turned to 21 .. i understood that its some kind of sexual satisfaction and i dont now its reasons as i mentioned it grew with me ..
so now i stoped doing this but returning to it rarely
the problem is what happened to my body? i dont know if there is any side effects or not
and did i lost my virginty through this process or not cause that would make a great trouble to me and my family..
