When posting on TER, and inquiring about the best place to advertise, please keep in mind that you're indeed posting in an advertising venue. Most women on TER are not here for our health/social interaction. We allow our ourselves to be reviewed here, we post here etc, specifically for the purpose of “marketing”. Do we like the social interaction? Sure. Are we aware of what we are doing? Yes.
Anyway, I bet a large percentage of men that frequent Backpage (if there was a way to ask them) would say that Backpage was the site Du Jour.
IMO, the success you receive on any given site is dependent upon the manner in which you choose to market yourself, and the type of men you are attempting to attract. You say you have a limited schedule due to “kids” etc, so it may not really matter WHERE you advertise, but rather HOW you advertise.
Perhaps you should create a website, and put your availability dates/times up on a calendar? That may help filter out the men that you would be unable to entertain? I would do the same in regards to your adverts.
PS. Post this on the PO board also, a lot of ladies will not post in public (for various reasons), you may get more candid/useful advice on the PO board.
Good luck!
