Hello and welcome!
First, on a beach you are going to be limited to only people really close to you, a couple of feet away.
For the club, I’d totally get some Ammo. There are a few options of what you could pair it with and that really just depends on your personality and personal preference.
I also suggest you go read An Introduction to pheromones; Names, Size, Strength, Use, Effects & Length of
and
The Snook’s big book o’ pheros for rookies
Those two will give you a good idea of what you might wannt to get to pair along with Ammo. The first link will also give you a good understanding of how pheromones work.
