Hey local91 - as I always tell new people - if you want a recommendation you should let us know a little more about what you enjoy. There are many great women out there but we all have different interests, body types, services, rates. It is hard for us to say who would suit you best without knowing a little more.
What age group appeals to you?
What body type?
Donation range?
I recommend that if you are looking for a girl to go easy on you and maybe give a bit of direction - as to what she likes and what you might like - you should definitely book an hour session instead of a half hour, that way you guys can chat a bit more and take things slow. Maybe start with a massage while you chat about what turns you on, establish a comfort level, and take it from there.
Half hour sessions are more - jump your bones and leave you going "holy hell, what just happened to me?". That certainly has it's place too, but can be a little overwhelming (and quick) for someone who doesn't have a lot of experience at this.
Best of luck with whoever you pick. Happy Hobbying.
