Flatbusher- dont know your case but are you sure the mother wasnt only looking for that because her son said he wanted dat?
Also, coming from flatbush and involved in shidduchim and im telling u im shocked and grossed out by what your saying. Think you just got an unlucky bad apple or batch. Cud be were dealing with more/less learning type but im under the impression that most sane mothers arent doing this.
