Whenever i am at work, i have sex. Thats what hookers do. Its not all we do, but whether its 5mins or 60mins, generally there is shagging involved.
All the relationships i have had while i have been in this profession, whether that be proper relationships, fuck buddies or one night stands, sex has been the beginning... its only after the initial sex that i have decided whether or not to take it to another level... or to lose their number never to hear from me again.
Fuck first, consider the potential later.
