Not relevant to the story, more on safety.
a) don't invite strangers to your house (on CL or otherwise) and don't go to a stranger house to meet for the first time. Meet at a safe bar or other safe public place where you can spend time talking to the person and be seen by others. If you decide to proceed to your home afterwards, don't tell your home address, just tell him 'follow me'. On another hand, if you decide to go to his house, ask for an address (just in case) and text it to a trusted friend.
b) avoid empty places, especially when dark (but during daylight too). Go walking where's public (even if you aren't yet sure of your looks). Approaching your car have keys ready in hand (make sure no one is too close), lock the car once inside. Have a pepper spray on a key chain.
c) yes, if you are pre-op but very passable, and plan to have a sex with a male, better let him know you are pre-op before you're alone with him (just in case).
d) have a reliable car and AAA (you don't want your car broken in a bad part of town with no help on the way).
e) be smart, don't do stupid things, don't be reckless
