Hi Alli
I'm not one of the ladies but maybe a humble monger's thoughts will help in some way.
FIRST if there is no reasonable profit or your heart isn't in it, then please don't do it! It sounds as though you realize that sort of thing just isn't for you, so then why do it??
I've seen some providers offering 15min quickie sessions but not sure how well that worked for them.
Keep in mind that certain rates and session lengths can attract as well as deter certain guys and you need to figure out who it is you want to spend your playtime with. If anything you might just offer it to your "special regulars" that you feel like you already have a good relationship with and you know will be coming back again for both long and short visits.
Instead I would suggest you turn your focus to try your best in stimulating men's interest both in mind as well as the loins. That is one thing that is great about the hobby boards. Some of the ladies here, and there are a few, that can manage to do that seem to do quite well. Look around and you'll spot the ones that have 'em eating out of her hand.
Interact, post fresh pictures, capture our borderline A.D.D. male brain's.
Hopefully you've gotten plenty of good advice already from the provider forum or through PM. good luck!
note: you have about six reviews associated with you that are actually about a different provider in missouri. just filed reports on all of the wrong ones so hopefully mods correct it soon
