they probably think either its A) too good to be true
and B) a sting

maybe contact girls directly with what you want, use your local whore boards to search reviews or girls' sites and find one who offers what youre looking for?
alot of girls wouldnt contact you on that ad i think cause of the 420 friendly reference, the prices youre willing to pay (whorings more n more a buyers market lately) and the simplicity of the work described
in short, yeah it sounds too good to be true
girls are used to getting haggled on their prices, asked for all sort of acrobatic sexual feats for bottom dollar, and being given teh runaround for references and whatnot
your ad sounds like heaven to a CL whore, so its probably being dismissed as a joke, or LE
im sure it and you are sincere, idaho, but girls are way more skeptical now and the whole hobbyist whore thing has gotten very jaded
its a shame
im sure any girl trolling CL in your area would have a great time with you lol you sound like alot of fun, but i dont know that youll get any quality responses
maybe ask burg for pointers on how to better approach this or reccomendations on girls that you might call? hes an invaluable resource on this very subject idaho

hope this helps

love, pretty
