Just a bit of balancing and additions to make being a Prostitute more rewarding.
Blowjob: Client pays $500, gets +1 stat for future achievement being "Blowjobs Received", client refills 50% of health, prostitute earns $500 and 3 score.
(2 minute cooldown)
Car Sex: Client pays $1000, gets +1 stat for "Auto Eroticar", client refills 100% of health, prostitute earns $1000 and 5 score.
(5 minute cooldown)
House Sex: Client pays $2500, gets +1 stat for "Sexy House Guest", client refills 100% of health, prostitute earns $2500 and 10 score.
(15 minute cooldown)
Also another law should be added being "Public Indecency" where if the prostitute offers services and a cop is nearby, both the client and prostitute receive +1 wanted.
