The problem with caring about labels and thus succumbing to social-psychological arguments is that once you start, there's really no stopping. If you're someone who doesn't want to be "those people", then you're therefore one of those other people who are apparently very sensitive about not being associated to those people.. which is equally as suspect, if not more. Only thing is is that it's less obvious to the less intelligent imaginary people you're pandering to by denying yourself options.. if you were denying yourself options, that is. If you're a happy stabber then that's fine too of course, whether for slightly silly reasons or not.

Of course there are more in-depth, no pun intended, tutorials around. But here's how I do it, if you'd like an extra point of reference.
Get two syringes, one of 10ml, one of 35ml. Any volume will do, but it's convenient to have one a multiple of the other.
Use lukewarm water, both for comfort and for purposes of dissolving your chemical. Depending on your powder, you might want to use warmer water which you then allow to cool down. I use a small witch's-cauldron-like piece of glassware with glass stirring rod, but any glass into which the small syringe can reach will do. (You also want a second glass from which to suck up water for both syringes.)
First administer plain water from the large syringe, as an enema. Wait ten minutes, then empty your bowels. Finally, administer your dosed water with the small syringe, sucked up from your cauldron glass.
For ease of access, bend over or squat a little. The syringe need not enter the rectum, just having the tip pressed against suffices. The enema gives you a chance to practice, as it's possible to get the angle wrong the first time, or when you're already tripping hard. But with gentle correction with persistently relaxed muscles, the right angle will become obvious soon enough.
For redosing no more enema is needed for at least 12 hours, depending on your diet.
