I’ve only been to amp twice and both times I finished almost immediately.   When I’m with escorts and irl, I have good control and can last a normal amount of time. My two experiences with amp were very different.   The masseuse was obviously very skilled but also very quick.  I don’t even think I was fully hard for more than a minute.  Is this common amongst others?  I asked to slow down but was just ignored lol

And move to another customer. What you can do is come to an amp after another session so you're not as fast to cum. But most sotrfront providers if you go for a while just try to get you off with a hj. Most storefronts are a conveyor belt thing. They handle volume and want to get back to their next turn in rotation.

you purchased?

 
My experience is that if it is a quality place that gives a good massage and lets you stay for whatever amount of time you purchased, the hand job will last at least 5 minutes.

 
I think you need to keep on searching for a better place.

...and they complain about the masseuses getting tired and sometimes giving up. I'm also a quick release and it surprises the masseuses since they never expect that from a female. People like us are their dream clients, lol

watch some porn and pop one or 2 off before heading off to the place
