Transsexual
YES, you fool, GO SEE HER! 
Ha! Just kidding.
Hey, I was SO nervous my first time, too. Hell, I still get nervous because I've not had too many experiences, and it's still brand new to me.
I think it's very, very smart--and brave--of you to be asking for help like this. Very smart, indeed.
Her reviews are excellent--nice track record. You don't get that by being flaky. So, I'd say call her, tell her you're a 1st timer, tell her you're nervous. Be totally honest.
Be sure to call her within 1-2 hours of when you'd like to see her. It's a rare gal that will set a date further in advance. Be ready for the 2-call set-up: You call to make the appointment. You call again after you get there or within a certain distance. This is common.
Follow through. You must go there if you commit on the phone. Let her take the lead! To help yourself feel better, you might consider a small gift, like flowers. She will appreciate the gesture, and it'll make things go smoothly. You see, it's like you're on date with a GG.
Have your donation in a white envelope. You are paying for TIME ONLY. Anything else is just stuff that happens.
Oh. You MUST CLEAN UP BEFORE YOUR VISIT. Take a shower, do whatever you would for a normal date.
O.k., that's about it, sweetie! Just relax, and you will have an absolute fun time!!!!
