I have no plans to add any UI other than the plugin's settings, that's outside of its scope.

Or should I adds 10s of buttons to VaM for every single one of them? That's really up to the scene creator to decide, and there are already many other plugins that can help with it.
I'd strongly recommend learning at least the basics of triggers, it's not that complicated. Then add any buttons you want to your scene with VaM's UIButton. Or if you want to have the button on the screen rather than in the scene, use something like

For example, if you have only one male with the plugin in the scene, the trigger for the penis emitter to start can be as simple as this:
