Male prostitutes are overwhelming hired by male clients, even if the sex worker himself identifies as heterosexual.
Boys at risk of becoming prostitutes would know this.
Edit:. I actually have known a guy that used bar style hookups to secure temporary lodgings but the transactional nature was more hidden. From the perspective of the women they had gone home with a nice guy and had a good time then discovered he needed a place to crash for a while but he would love to help around the house and babysit for her.
