Does It sound like my brother was ually attracted to me?

this can be due to excess of wish of getting i think that he tries to do with you because he is having a flame of doing it but as you have mentioned that he is 20 and according to my point of view how can a brother think of doing with his sister this can be due to the bad friend circle in the adolescent age i am also 16 and can understand you and one reason of this could be that your parents have not taken care of him at the age of growing you should give him one chance of being a good human and if he don't obeys you after giving a chance then you should forget about him that he is your brother..
