Turkey and the Ottoman empire in general IIRC historically had "peg houses" or peg boys, which seems clear enough. Oddly Muslims which may have a very conservative view of sex with women, can still participate in activities with young boys. But it would seem that the thinking is the shame is to be the penetrated one (i.e. the "woman"), not the penetrator (the male). Seems the ancient Greeks influenced these cultures more than expected.
I find facinating
@midnight orange assertion of it possibly being a "talisman for elite status which means that they are not subject to the law like normal people." Yes, only the corpulent (money, power, body) could be so corrupted, so vile as to thumb their noses at the laws of God and conformity of culture. So among themselves it is taken for a sign of power. So interesting.
