Before I tell you what to do, I want to tell you that it seems that many people have this situation, and this is also the reason for the emergence of "German orthopedics", that is, a brother and sister have sex, and their father finds out that they directly break their bones and finally go to German orthopedics for treatment.
To tell the truth, there seems to be no good solution to this problem, and we can only do it step by step, so don't do those too intimate actions again. Men and women are always different, and little boys will not sleep with their mothers when they grow up. No matter how deep the love between brother and sister is, at this age, there will be a little bit of gender resentment.
Needless to say, brothers and sisters are against human relations. If you want to think that this is an abnormal development trend, you'd better recognize it in time and stop being so affectionate. Intimacy and intimacy are two different things. Brothers and sisters' blood is thicker than water, but at this age, cuddling every day is not appropriate.
