Good day nairalanders

Just two days ago I was discussing with some colleagues from a particular tribe in Nigeria ( name withheld) and in the course of our discussion these two told me that even at their age as young adults that they bathe with their grown up siblings, I was shocked and found it hard to believe, but I saw that they were damn serious.

I know that there are various cultures and these cultures have various practices which can bring cultural shock to one whom is not from such cultures, however going with the look of things and from all sensibilities, I feel it ain't right for grown up siblings to bathe together especially if they are opposite sexes,I have heard of some irresponsible acts that stem from that...

But my question is;
My good nairalanders is it normal by you that matured adults bathe together with their grown up siblings as opposite sexes?

Not normal and not advisable.

That's really wierd! I can't encourage such practice because of the risks that comes with it. If it's same gender, no problem, but opposite gender issa big NO!
