I'm new here myself but punted for a while.
You should post the link it could make all the difference. If you really don't want to make sure you search for their name and id number on here. Things that should make you think twice:
If there no reviews at all on here
Or lots of poor reviews obviously
If they are newly registered on aw or any other site (they might be a gem but you'll never know until too late, which is ok for regulars but not as a first pop in 4 years)
Some nationalities have poor a rep and don't seem to fully adhere to the trades description act
With regard to shooting your bolt as soon as you walk in, so what, just make sure you check they'll let you cum as many times as you can. I can't believe getting hard again will be a problem.
Can't offer any thoughts on pill popping I'm afraid (which I know was your actual question) as I've not done this.
Good luck and keep us posted
