Hey Dude! Why do you want to give invitations to STDs and ruin your life. You never know what the prostitute has ever gone through.
If you are so desperate for a relationship, then why not try some dating site that give you the option of even
sex personals if you want to have sex with them.
I would suggest you to take precautionary measures if your intending to venture into a sex with a prostitute.
Any ways, good luck...
