Hello! My experience with rolling isn't huge. It seems like if you're into E you are REALLY into it. But I've had beans a couple times, Molly a few more times, 'Sass' kind of a lot and Methylone/Butylone many many more times.
All I can say is do it where others around you are either taking it too, like a party, or are cool with you taking it.
I took a couple beans on my way to my cousins once (was told there was a party) and when I got there it was maybe 5 people just sitting around a fire... with babies! And my cousin who invited me over isn't too cool with drugs (I thought he'd at least be drinking) so I had to hide the fact that I was rolling HARD! And it sucked having to do that.
Other than that... everything and everywhere is pretty awesome on it. For me at least.
Also, my gf and her friends are into light shows and stuff like that. If you're into that than I'd suggest things like glow sticks etc... Or like one time we just had a strobe light in my room with glow in the dark paint and music.
But just do whatever you're into and it'll just make it better. Sometimes just laying on the floor talking is a great experience. Especially if its just an intimate setting like yours sounds.
