the most important thing about your first time is to just RELAX and enjoy yourself. My first time wasnt with an escort but have been to a few in the past. She will make you feel at ease if you tell her its your first time, and take it slow if you get excited to quick or something (so easily done with a hot shemale)
But yeah like i said enjoy it and make sure you fulfill all fantasys you have
I guarantee youll go back for more we all do!
