In the month I was on SA, I probably texted about ~25 girls. Of those, I ended up sleeping with four and had repeat encounters with two (both of which could host). I eliminated one of those after ~2 months, when she tried to have a session during her period (without informing me of that beforehand) and wanted her full fee after I opted out. The one SB I have now I've been seeing since last Feb. She is beautiful, sane, discreet, low cost and hosts; in other words: a keeper. I see her about 2X a month. For weeks we do not meet, I have other options. These include spa girls who see me outside the spa on their rest periods and one Asian civvie. At this point, I don't hit AMPs nearly as much as I used to; probably one every 5-6 weeks.
Personally, I found a number of things exhausting about SA: the texting, the drama queens, the royal wannabees (girls with an inflated sense of their worth), the fake posers (women in the 30s and 40s pretending to be in their 20s), the ghosts (who never show up at meetings) and the scammers. It is a fair amount of work to arrange a meeting that actually results in sex. And I make clear that I want to go right to the main event, so I don't F-around with formalities. A new encounter can be risky too; I would not put it past either LE or criminals to entrap someone. I ran into a few scammers that I posted about on other threads (one of whom still emails me on occasion, LOL). If you crave variety or are into "The Hunt" as an end in itself, then it makes sense to be a long term SA member. However, if you just want to find a few gems or like simplicity, then it makes more sense to be a member for 1-2 months, harvest as many contacts as possible, and then live off that bounty for as long as you can.
