I would think that 1 month in advance is good,especially if you've got someone in particular in mind or if you want her for more than 1 hour or if you want a very desirable time frame{such as Saturday evenings,or Friday evening rush hours or around lunchtime Mon-Fri}.If you're nervous about it,then email her first to establish contact,then call her.Remember,it's guaranteed! There's no mind games like will she or won't she.Just figure out what you want,read the reviews on the ladies you're interested in and make contact with your choice.Remember,she's going to be having sex with somebody,tell yourself it might as well be me!

Re:how early to contact

thanks a ton all o'you for the suggestions.

Three to four weeks in advance via e-mail.  Be sure you indicate you are a newbie for screening purposes now and then for maximum enjoyment at the appointed time.  Go ride the bike.
